Abstract. With the rapid development of the world aviation industry, the demand for aeronautical
titanium alloys is increasing day by day. A stable and rapid development of the titanium alloy
market has been formed. Based on the analysis of the industrialization status quo in the United
States, Russia, Japan and China, the problems in the development of the aeronautical titanium alloy
industry in China are put forward. In order to solve these problems, it is suggested to develop
advanced titanium alloys and processing technologies, adjust the industrial structure and further
improve the material standards for aeronautical titanium alloys.
Introduction
Now, titanium alloys have become one of the new materials for aviation, due to their good
comprehensive performance [1,2]. Since titanium alloys were applied firstly for manufacturing
fighters in the United States in the 1950s, titanium alloys have been used primarily in aircraft
engines and aircraft skeleton structures due to their superior properties such as the specific strength,
fracture toughness, heat resistance and corrosion resistance.
In recent years, the world's titanium alloy processing technology has been rapidly developed, and
the production and consumption of titanium alloys have reached a high level. China's titanium is
rich in resources, and the reserves are the most in the world. It has become the world's fourth largest
titanium industrial country with the complete industrial system and production capacity after the
United States, Russia and Japan. Strengthening the research and application of titanium alloys for
aviation and promoting their industrialization are of great significance for the development of
Chinese aviation industry. In this paper, the current status of the aeronautical titanium alloy industry
in four major titanium industrialized countries are introduced in detail, and the development
strategies of Chinese aeronautical titanium alloy enterprises are discussed.

Titanium alloy products shipped in the United States in 2011 were 45,500 t, including forgings
and ingots of 40%, plates of 40%, wires and bar of 15%s, and others of 5%. Titanium alloys are
mainly used in military and civil aircraft engines and airframes. From the perspective of industrial
structure, the three titanium and titanium alloy production enterprises: TIMET, RTI and ATI, have
determined the technical level and development direction of the United States titanium alloy
industry.
TIMET is one of the world's leading producers of titanium alloy products and it is also the largest
supplier of titanium alloys in the United States. TIMET (PCC) has sold a total of $7.2 billion in
2011, and titanium alloys for aerospace industry such as aircraft engines as its main products. RTI is
a professional manufacturer of titanium and titanium alloys for over 50 years. It is mainly engaged
in the production and sale of titanium alloys for aviation, and it is the main supplier of Boeing,
Airbus and British Aerospace Systems. The shipment volume of titanium and titanium alloy
products was 6700 t in 2011 and 7500 t in 2012. ATI is the largest special steel producer and the
third largest titanium and titanium alloy producer in the United States. It is also the largest and most
diversified professional metal producer in the world. In 2011, ATI acquired forging giant Ladish for
$900 million, making it a true titanium and titanium alloy manufacturer by integrating titanium
ingots, forgings and sheet metal production. ATI's products are mostly used in aeronautical titanium
alloy products. Its main products include flat rolling products, high performance metals and
engineering products. The shipment volume of titanium and titanium alloy products was 115,000 t
in 2010 and 12,000 t in 2011.
Russia
Russia has the worlds largest full-process titanium alloy producer - VSMPO-AVISMA. In 2011,
the output of titanium and titanium alloy products in Russia was 29,100 t, of which
VSMPO-AVISMA produced 24,200 t. In 2012, the output reached 32,400 t, of which 40% was
used to meet domestic demand and 60% was exported.
VSMPO-AVISMA actively develops relationships with Western companies. On June 30, 2008,
VSMPO-AVISMA signed a framework agreement with Airbus under EADS (European Aviation
Defense Company) for the supply of aeronautical titanium alloys. The agreement stipulates that
VSMPO-AVISMA will supply the required titanium alloys to Airbus under EADS in 2020. The
agreement is worth $4 billion. VSMPO-AVISMA also signed new long-term contract to supply
titanium with French aircraft engine manufacturer SNECMA under SAFRAN, supplying titanium
alloy plates, rods and cakes to SNECMA and other companies that have joined the SAFRAN Group
to produce aero engines. It is estimated that the total revenue of the current contract will reach $300
million. In order to further expand its revenue, VSMPO-AVISMA strives to increase the added
value of its products, such as increasing the proportion of forgings and re-selling its products after
mechanical processing. The main task of the company in recent years is to continue the production
of titanium and titanium alloys, to strive to account for one-third of the world titanium market share
and to strengthen the relationship with partners. Now the company's production has entered a period
of rapid development, but also turned to the field of further-processing.
Japan
Japan has owned a complete titanium industry chain with reasonable industrial structure and
advanced technology. In Japan, there are five companies producing titanium alloy products, namely
Nippon Steel & Sumitomo Metal, JFE Stainless Steel, Kobe Steel, Datong Special Steel and Aichi
Steel. In Japan 85% of titanium alloy products are used in fields other than aviation such as
chemical, electric power, automotive, construction and medical [4]. At present, with the rapid
development of the aviation industry, the Japanese titanium alloy industry has signed contracts with
aircraft component manufacturers. At the beginning of January 2016, Japan’s Nippon Steel &
Sumitomo Metal and the SAFRAN Group of France’s SNECMA reached a new agreement on the
long-term supply of titanium alloy billets for aviation. In July 2016, Kobe Steel began mass
production of large titanium alloy forgings for Airbus A350XWB.
China
China's titanium industry started in the first five-year plan of the country, that is, in 1954. In the past
64 years, China's titanium industry has experienced three important stages of development: the
start-up period (1954~1978), the growth period (1979~2000) and the rise period (2001~present)
[5,6]. The rise period is a soaring period for China to become a major titanium industry in the world.
Under the background of rapid development of the national economy and accession to the WTO,
the titanium market expanded significantly, and social capital was spontaneously entered the
titanium industry. As a result, the level of the titanium industry increased significantly, and research
and production showed a thriving situation. Titanium production rose sharply year after year,
creating new records every year as shown in Figure 1. In 2016, the total output of titanium ingots in
27 titanium ingot manufacturing enterprises in China was 66,500 t, and the total output of titanium
alloy products in 30 titanium processing materials production enterprises was 49,500 t, which far
exceeds other titanium industrial countries such as the United States, as shown in Table 1. However,
from the application field, China's titanium industry mainly produces general industrial titanium and
titanium alloy products. In 2006, the demand for aeronautical titanium alloys accounted for only
9.7% (1338.8 t) of the total demand for titanium in China. In 2007, it rose to 17.2% (4061 t). In
2008, it was affected by the economic crisis and fell back to 12.8% (3575 t). Meanwhile, the
average value of aviation field in the world is 50% and the United States is more than 70%.
Figure 1. Changes in output of titanium and titanium alloy products in China (1964~2016).
In recent years, China's large aircraft, space station, and lunar exploration project (Chang'e
project) will produce a large number of aerospace titanium alloy demand. Especially in large
aircraft projects, the application of aerospace titanium alloy will gradually increase. The launch of
major projects in the aerospace industry is an opportunity and challenge for the China's aviation
titanium industry. In response to these trends, China has made great efforts to promote the research
and large-scale production of high-performance aeronautical titanium alloys, and achieved some
achievements. Taking the market as the guide, BaoTi Group has developed large diameter bar and
superplastic forming sheet of Ti-6Al-4V alloy for aeronautical structural parts. In addition, it has
passed the quality system, process technology and product certification and audit of Boeing
Company, French Aerospace Company, European Airbus Company, Rolls Royce Company of
Britain, GOODRICH Company and other companies, and can provide products that meet the user
requirements.
Prospective Analysis of Aeronautical Titanium Alloy Market
The demand for titanium alloys for various military aircraft and civil aircraft is increasing. Titanium
alloys used in F15, F22, F35, F117, B1, B2 and V22 fighters are 27%, 41%, 27%, 25%, 21%, 26%
and 16%, respectively [8,9].
Wade Leach [10], vice president of ATI market and product management, predicts that by 2035,
the global formations number of commercial aircrafts will reach 50,000, which is more than
doubled from the number of commercial aircrafts in the world in 2014. Henry S. Seiner, vice
president of business strategy at TIMET, reported that in 2014, a total of 3,160 aerospace engines
were produced worldwide, and titanium alloys will continue to be the main material for jet engine
compressors. Michael Metz, President of Russia VSMPO, said that by 2021, the total demand for
titanium alloys in Russia will reach 13,100 t. William T. Shaffer, Boeing's director of materials and
standards, pointed out that 38,050 new aircrafts will be delivered in the world by 2034. The main
type of aircraft is a single channel aircraft with 26730. According to Shaffer, the Boeing 747-8 has
6 million parts and the Boeing 777 has 3 million parts. The number of parts purchased each year
reaches 1 billion, costing $43 billion. Waldir Gomes Concalves, senior vice president of global
customer support and services at Embraer, predicted that 70~130 seat commercial aircraft of 6,350
will be delivered worldwide in the next 20 years, and the worth is $300 billion. Meanwhile, 9,250
business aircrafts will be delivered worldwide in the next 10 years, and the worth is $265 billion.
Thus, the market demand of aeronautical titanium alloys in the United States, Russia, China and
other countries in the world is very huge, and will show a growth trend in the next decade or even
decades.
Development Strategy of Titanium Alloy Enterprises for Aviation in China
Problems in the Development of Titanium Alloy Industry for Aviation
At present, Chinas titanium industry has still some problems to be solved in the important
application fields such as aeronautics and astronautics.
(1) The basic research on the heat-resistant titanium alloy system with a service temperature of
650 °C and above for aero engines is insufficient, and the industrialization of new
technologies is progressing slowly. It restricts the application of heat-resistant titanium alloys
in new types of aeronautical power system.
(2) The research on the industrial production technology of high performance titanium alloy
products with shorter process and lower cost is insufficient.
(3) The existing technical standards for aeronautical titanium alloys (GB, GJB) can't meet the
requirements of current applications of new alloy grades.
Development Strategy
(1) Develop advanced titanium alloys and processing technologies, and promote the
industrialization of new technological achievements. Now, many countries are carrying out
research on new titanium alloys with higher service temperature, making some achievements.
For example, the service temperature of Ti-Al intermetallic alloys such as Ti3Al and
Ti2AlNb-based alloys breaks through the traditional titanium alloys [2]. NASA predicts that
by 2020, the application of Ti-Al intermetallic alloys on aircraft engines may reach 20%. In
China, the development of Ti-Al intermetallic alloys such as Ti2AlNb-based alloys is
basically synchronized with that of the United States and Europe. The systematic research on
alloying and microstructure design of the alloy has been carried out, and the breakthroughs
have been made in the application field such as satellites and missile engines. Recently, the
National Key Laboratory for Precision Hot Processing of Metals (Harbin Institute of
Technology) has studied the fabrication of Ti2AlNb-based alloys by elemental powder
metallurgy technology. The Ti2AlNb-based alloys with ultra-fine microstructure and
excellent mechanical properties were produced from cheap elemental powders [11].
(2) Promote the adjustment of industrial structure and produce high value-added titanium alloy
products with shorter process and lower cost. There are four main ways to reduce costs:
firstly, to expand production scale on the basis of increasing demand; secondly, to promote
technological progress and improve management level of enterprises; thirdly, to research
new technology and processes; and fourthly, to develop new titanium alloys with lower cost.
In order to realize the large-scale production of aeronautical titanium alloys, on the one hand,
it has reached the economic scale by technological advancement and tapping the potential of
old enterprises, and on the other hand, it has built a large-scale production plant for titanium
alloy products.
(3) Further improve the standards for aeronautical titanium alloys. In the future, the complete
work of the standards for aeronautical titanium alloys should be opened depending on the
industrialization of titanium alloys. The types, specifications and processing technology of
the newly developed titanium alloys should be formulated as the corresponding national
standards, national military standards or aviation industry standards.
Conclusion
At present, China's aeronautical titanium alloy industry is facing new development opportunities,
especially with a stable and expanding world aviation market. Under this situation, it is necessary to
intensify scientific and technological innovation, develop advanced titanium alloys and processing
technology, and develop high value-added products of titanium alloys. In addition, it is very
important to promote the adjustment of industrial structure, reduce the cost of titanium alloy
products, and further complete the standards for aeronautical titanium alloys for aviation.

... Titanium alloy is a lightweight alloy that emerged in the 1950s. It is widely used in aircraft structural components (landing gear, crossbeams, skins, etc.) and engine components (blisk, engine casing, fan plate, etc.) because of its high specific strength, good oxidation resistance, excellent resistance to high temperature, etc. [1,2]. TC4 titanium alloy accounts for more than 50% of all titanium alloys used [3,4], and is a typical material commonly used in the aviation industry. ...

By introducing a high concentration of electrolyte into the working medium of conventional short electric arc machining (SEAM), we have realized the removal of surface defects of SEAM using electrochemical machining (ECM) during the discharge of SEAM. This process is called short electric arc-electrochemical (SEAM-ECM) combined machining. The forms of power excitation mainly use pulsed and constant voltage DC. Therefore, this research first reveals the arc-breaking and action mechanism of SEAM-ECM combined machining under two excitation forms by single-pulse simulation and experiment. The results show that DC excited arc-breaking is an adaptive arc-breaking over the discharge gap; the intensity and duration of ECM action of DC excitation are higher than that of pulsed excitation; at the same current strength, the arc-breaking time of DC excitation is about three times more than that of pulsed excitation (duty cycle of 55%). In addition, continuous discharge experiments are conducted to verify the machining effect of SEAM-ECM combined machining. The results show that DC excitation tends to form a continuous arc during machining, aggravating copper electrode loss and reducing the workpiece’s dimensional accuracy and the material removal rate. The concentrated discharge energy also produces deeper discharge pits, making the workpiece surface rougher relative to the pulsed excitation. The machining differences between the two excitation methods at different voltages are compared, showing that a balance exists between SEAM and ECM under suitable machining conditions.
... However, this interpretation is erroneous because even electrically powered aircraft would need rigorous assessments of millions of parts made from various materials with their own environmental impacts. The development of a conventional commercial airplane lasts approximately six years and involves the design of up to 6 million parts (Sim et al., 2018). Once a commercial aircraft is acquired and brought into service, it stays in use for a long time, often more than 20 years (Flüthmann et al., 2020). ...

The current aviation sector has been shaken by COVID-19, but a few years prior, the industry was experiencing a time of prosperity never seen before. These years were marked by the introduction of new models and record sales. In particular, two cases stood out from the rest: the Boeing 737 MAX and the Airbus A320neo. Such overwhelming success in sales was partly because in essence, these are quite traditional and familiar aircrafts that featured improvements in some critical systems, notably in the use of newer engines. Current projections suggest that the pre-COVID growth rate of aviation will resume in a few years, which raises global concerns regarding the ecological burden of conventional aircraft and their resulting limitations. By reviewing the green technologies likely to be incorporated into conventional aviation over the next 30 years, we explore the limits of the industry's current approach. To this end, we reconstruct an already validated life cycle analysis model to assess a fleet of aircraft and analyze the impacts of these new technologies on emissions. Based on data from the literature, predictions are made for optimistic and pessimistic scenarios in a post-COVID world. The results are compared with the globally established targets set by the International Air Transport Association (IATA). Simulations show that a future based solely on conventional aircrafts using evolutionary technologies is of great concern. There is an important need to promote a radical departure from the current aviation models to accommodate the growing demand for aviation with a green future.
... The forth is complex geometry. Because the components are designed more and more integrally, their geometry with closing cross sections and irregular curved surfaces is much more difficult to form than the traditional divided structures [4][5][6]. ...

The variable cross-section thin-walled hollow components of titanium alloys are increasingly used in the power and fuel systems of aerospace vehicles, which play an important role in reducing the weight of the structure, improving the service performance and reliability, etc. However, the formability of titanium alloys is very poor at room temperature, so it is very difficult to manufacture the complex thin-walled hollow components. Hot gas forming is an efficient strategy to form integral hollow components of titanium alloys. In this paper, some progress on this forming technology from the author’s lab is presented, which includes the deformation mechanisms, constitutive equations, process simulation, technological innovations and typical applications. Based on the research about the deformation mechanisms, the unified constitutive model was developed. Then the deformation process and microstructure evolution of gas forming could be predicted numerically. According to the difficulties of different components with different materials and geometries, new forming process with non-uniform temperature field, new heating system and new tooling strategy were presented. The new technologies were applied to form the components with irregular cross sections and components with large expansion ratios, meeting the application demand of aerospace industry, etc.
... With the increasing demand for light weight structures whilst satisfying in-service properties, tubular and panel components manufactured from titanium alloys are gaining increasing popularity in various industries, such as aircraft, aerospace and marine, due to their excellent mechanical properties [1,2]. Moreover, newly designed titanium alloy components for next generation applications require continuously increasing dimensional accuracy, material properties, and shape complexity whilst enabling ease of integration and reliability [3][4][5]. However, forming of titanium alloys at cold 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 A c c e p t e d M a n u s c r i p t F o r R e v i e w O n l y 2 conditions is challenging due to the high deformation resistance, limited ductility and severe springback, resulting in the extensive development of hot forming processes [6]. ...

Complex thin-walled titanium alloy components play a key role in the aircraft, aerospace and marine industries, offering the advantages of reduced weight and increased thermal resistance. The geometrical complexity, dimensional accuracy and in-service properties are essential to fulfill the high-performance standards required in new transportation systems, which brings new challenges to titanium alloy forming technologies. Traditional forming processes, such as superplastic forming or hot pressing, cannot meet all demands of modern applications due to their limited properties, low productivity and high cost. This has encouraged industry and research groups to develop novel high-efficiency forming processes. Hot gas pressure forming and hot stamping-quenching technologies have been developed for the manufacture of tubular and panel components, and are believed to be the cut-edge processes guaranteeing dimensional accuracy, microstructure and mechanical properties. This article intends to provide a critical review of high-efficiency titanium alloy forming processes, concentrating on latest investigations of controlling dimensional accuracy, microstructure and properties. The advantages and limitations of individual forming process are comprehensively analyzed, through which, future research trends of high-efficiency forming are identified including trends in process integration, processing window design, full cycle and multi-objective optimization. This review aims to provide a guide for researchers and process designers on the manufacture of thin-walled titanium alloy components whilst achieving high dimensional accuracy and satisfying performance properties with high efficiency and low cost.

A high strength and ductility Ti‒22Al‒25Nb alloy was fabricated from high energy ball-milled powder by spark plasma sintering. The pre-alloyed powder with a normal composition (at %) of 53 Ti, 22 Al and 25 Nb was firstly ball-milled for different milling times, and subsequently consolidated by spark plasma sintering. The effects of ball-milling time on the microstructure and mechanical properties of the ball-milled powder and sintered compact were investigated. The Ti‒22Al‒25Nb alloy sintered by SPS at 950 °C for 10 min under a pressure of 50 MPa from the ball-milled powder showed the microstructure with a large amount of ultrafine/nano O-phase. The best balance of tensile properties was exhibited in the Ti‒22Al‒25Nb alloy sintered from the ball-milled powder for 20 h; the yield strength, the tensile strength and the elongation to failure were 1092 MPa, 1105 MPa and 9.4% at room temperature respectively, exceeding other coarse grain Ti‒22Al‒25Nb alloys fabricated by other powder metallurgy methods in the comprehensive tensile property. The precipitation of secondary phase, the grain refinement and the change of residual dislocation density in the sintered alloy directly affected the tensile properties of the sintered alloy.
