Ti2AlNb intermetallic alloy is a typical high-temperature resistant material with exceptional mechanical properties and is beneficial to enhance the performance of aero-engine components. However, machining of Ti2AlNb intermetallic alloy is extremely difficult, and ensuring the required surface integrity is an ongoing challenge, especially when aim...

Ti2AlNb intermetallic alloys, which belong to the titanium aluminum (TiAl) family, are currently being extensively researched and promoted in the aerospace industry because of their exceptional properties, including low density, high-temperature strength, and excellent oxidation resistance. However, the excellent fracture toughness of the material...

Aero-engines, the core of air travel, rely on advanced high strength-toughness alloys (THSAs) such as titanium alloys, nickel-based superalloys, intermetallics, and ultra-high strength steel. The precision of cutting techniques is crucial for the manufacture of key components, including blades, discs, shafts, and gears. However, machining THSAs pos...

Ti2AlNb intermetallic alloy is currently the most promising lightweight high-temperature resistant material in the aerospace industry, owing to its high specific strength, favourable room temperature plasticity, outstanding temperature strength, and creep resistance. High speed cutting technology is characterized by low cutting force, minimal therm...

Cubic boron nitride (cBN) superabrasive grinding wheels exhibit unique advantages in the grinding of difficult-to-cut materials with high strength and toughness, such as titanium alloys and superalloys. However, grinding with multilayered metallic cBN superabrasive wheels faces problems in terms of grain wear resistance, the chip storage capability...

This paper presents a comprehensive review on the types of machining deformation and mechanism analysis, as well as the machining deformation control methods of aero-engine thin-walled casings. The different types of machining deformation (e.g. deformation caused by positioning and clamping process, cutting forces, residual stress, and chatter) of...

This study investigated the buckling performances of stainless steel toroidal shell segments under uniform external pressure. The toroidal shell segments used in this study exhibited a nominal section radius of 70.5 mm, nominal wall thickness of 1.346 mm, and nominal rotation radius of 138 mm. A total of 12 toroidal shell segments were manufactured...

The purpose of this paper is to elaborate the non-linear collapse of externally pressurized resin toroidal and cylindrical shells, along with a comparison between a toroid and cylinder. For this purpose, the collapse characteristics, critical loads, and imperfection sensitivities of volume equivalent shells were numerically evaluated for the first...
