Hot tearing is one of the most severe and irreversible casting defects for many metallic materials. In 2004, Eskin et al. published a review paper in which the development of hot tearing of aluminium alloys was evaluated (Prog. Mater. Sci. 2004; 49: 629-711). Sixteen years have passed and this domain has undergone considerable development. Neverthe...

Chemical short-range order (CSRO) refers to atoms of specific elements self-organising within a disordered crystalline matrix. These particular atomic neighbourhoods can modify the mechanical and functional performances of materials 1-6. CSRO is typically characterized indirectly, using volume-averaged (e.g. X-ray/neutron scattering) 2,7,8 or throu...

Al-Mg-Zn-(Cu) crossover alloys, embracing the advantages of traditional 5xxx and 7xxx series aluminum alloys, are being designed to achieve a better trade-off between ductility and achievable strength. In this study, we achieve an excellent strength-ductility combination in a high Cu-concentration Al-4.0Mg-3.0Zn-1.5Cu (wt.%) crossover alloy. The ef...

Architected materials that consist of multiple sub-elements arranged in particular orders can demonstrate a much broader range of properties than their constituent materials. However, the rational design of these materials generally relies on experts' prior knowledge and requires painstaking effort. Here, we present a data-efficient method for the...

Twins and 9R phase (a structure containing a high density of stacking faults) have played important roles in simultaneously improving strength and strain hardening capacity of low-to-medium stacking fault energy (SFE, smaller than 50 mJ/m²) metallic materials. Due to the high SFE (166 mJ/m²) in pure face-centered-cubic Al and its insensitivity to m...

Al-Mg based alloys are known to experience dynamic strain aging (DSA) at room temperature, which is often associated with the diffusion of mobile Mg atoms to dislocation segments temporarily arrested at obstacles (e.g., forest dislocations) upon deformation in the DSA regime. With the emergence of new promising high Mg-content (> 6 wt.%) Al-Mg allo...
Article
In this study, we combine dynamic strain aging and dynamic precipitation by simple pre-deformation instead of usual artificial aging in a high Mg-content Al–Mg–Zn based crossover alloy. With this strategy, both the dislocations and shearable precipitates are manipulated to concurrently increase the flow stress and strain hardening rate, equipping t...

Inferior absolute strength and dissolution properties are the main bottlenecks for the widespread application of dissolvable magnesium alloys in complex working environments for unconventional oil and gas resources. Here, a novel functional peak-aged Mg-9.5Gd-2.7Y-0.9Zn-0.8Cu-0.4Ni (wt.%) alloy for fracturing tools is reported, and it possesses an...

Atom probe tomography (APT) is often introduced as providing “atomic-scale” mapping of the composition of materials and as such is often exploited to analyze atomic neighborhoods within a material. Yet quantifying the actual spatial performance of the technique in a general case remains challenging, as it depends on the material system being invest...

Currently, there is a tendency towards breaking through conventional 5000 series aluminum alloys framework and designing heat-treatable Al-Mg based alloys with the improved mechanical properties. Here, based on a small amount of experimental work and our previously developed Integrated Computational Materials Engineering (ICME) framework, the autho...

In this work, the dynamic response at a similar high strain rate of a series of Mo-doped CoCrNi medium entropy alloys, i.e., CoCrNiMox (x = 0, 0.1, 0.2), was investigated via a split Hopkinson pressure bar (SHPB). We found that with the Mo amount increasing from 0 to 0.2, the yield strength nearly doubles, from ∼450 to ∼800 MPa, under such a high s...

The effects of grain size on the deformation behavior in a metastable Fe40Co20Cr20Mn10Ni10 high-entropy alloy (HEA) were investigated. The dislocation substructures with two different grain sizes of 12 μm (FG) and 41 μm (CG) upon straining were revealed, of which the strong grain size dependent of martensite phase transformation was observed. The H...

The coupling of computational thermodynamics and kinetics has been the central research theme in Integrated Computational Material Engineering (ICME). Two major bottlenecks in implementing this coupling and performing efficient ICME-guided high-throughput multi-component industrial alloys discovery or process parameters optimization, are slow respo...

Nanoscale L12-type ordered structures are widely used in face-centred cubic (FCC) alloys to exploit their hardening capacity and thereby improve mechanical properties. These fine-scale particles are typically fully coherent with matrix with the same atomic configuration disregarding chemical species, which makes them challenging to be characterized...

New 7xxx aluminum alloys with high alloying contents are being designed, which could induce serious hot tearing defects during direct-chill (DC) casting. Among all factors affecting hot tearing of 7xxx alloys, undoubtedly alloying elements play a significant role. In this study, the effect of main alloying elements (Zn, Mg, and Cu) on hot tearing o...

The effect of Zn addition on the hot tearing susceptibilities of non-refined Al-xZn-2Mg-2Cu (x = 2-12 wt pct) alloys was investigated via direct crack observations and load response measurements. The obtained experimental results were compared with the predictions made using a modified Rappaz–Drezet–Gremaud (RDG) hot tearing model. Both the minimum...

Cold cracking is a severe challenge during the direct-chill casting of high-strength 7××× series aluminum alloys. A finite element method (FEM) simulation combined with a cold cracking criterion has been demonstrated to possess obvious technical advantages in cold cracking prediction. However, the current absence of mechanical properties and effect...

During the production of high-strength 7××× aluminum alloys, hot tearing has set up serious obstacles for attaining a sound billet/slab. In this research, some typical 7××× alloys were studied using constrained rod casting together with the measurement of thermal contraction and load development in the freezing range, aiming at investigating their...

The influences of grain size and morphology on the hot tearing susceptibility of AA7050 alloy inoculated with Al-5Ti-1B master alloy were investigated by the authors. It was found that with the optimal addition of Al-5Ti-1B, coarse columnar grains were transformed into fine globular equiaxed grains. Moreover, due to the changes of grain size and mo...

The hot tearing susceptibilities (HTS) of some AA7×××alloys, AA7050, AA7055, AA7085 and AA7022 were evaluated with constrained rod casting (CRC). Thermal contraction behaviors during solidification were measured as well in a T-shaped setup. The results showed that alloys with HTS from high to low were AA7055, AA7085, AA7050 and AA7022.

For an ICME (Integrated Computational Material Engineering) modeling framework used for the age-hardening aluminum alloy design and heat treatment parameters optimization, it is critical to take into account the geometric shape of precipitates, as it is tightly related to the precipitation kinetics and particles' hardening effect. The aim of this project is to present such an ICME modeling approach to describe the precipitation of non-spherical hardening particles during aging treatment and predict the final yield strength.

7xxx aluminum alloys are widely applied in aerospace due to their excellent properties. Nowadays, to attain high performance such as high strength-to-weight ratio, high damage tolerance, and good corrosion resistance, and so on, new 7xxx alloys are being developed towards high alloying content and large ingots size. These tendencies could induce serious hot tearing defects during direct-chill (DC) casting. Among all factors affecting hot tearing of 7xxx alloys, undoubtedly alloying elements play a significant role. However, to date, limited researches have been performed to investigate the influence of alloying elements (including grain refiners, main elements, and minor elements) on the as-cast microstructure and hot tearing susceptibility in DC casting of 7xxx aluminum alloys. In the project, this topic is systemically investigated by some experimental and theoretical approaches.
