The research and development of high-temperature titanium alloy standard parts is mainly concentrated on the high-temperature titanium alloy at 600℃. The domestic standard parts of titanium alloy are mainly developed by the Institute of Metallurgy, Chinese Academy of Sciences. The composition of Ti60 titanium alloy is a near-α heat-strength titanium alloy improved on the basis of Ti-5.5Al-4Sn-2Zr-1Mo-0.3Si-1ND-0.05CTI55, and its comprehensive properties are improved by ND strengthening. The long working temperature of this alloy can reach 600℃, which is suitable for the compressor discs, drums and blades of the high-pressure section of aircraft transmitters. Domestic research on high-strength titanium alloys is mainly concentrated on TB8TC21 and other brand titanium alloys (developed by Northwest Nonferrous Research Institute). The composition of TB8 titanium alloy is Ti-15Mo-3Al-2.7Nb-0.2Si medium-stable β-type titanium alloy. In addition to consuming plates and strips, TB8 titanium alloy can also produce foils, wires, tubes, bars and forgings. This plate is mainly used to manufacture aircraft cold-formed sheet metal parts of medium complexity, which can replace structural steel with strength grade of 30CrMnSiA. The newly developed TC21 titanium alloy has stable mechanical properties and matches with the strength, plasticity, fracture toughness, crack growth rate and other indicators. It is a high-strength and high-toughness damage-tolerant titanium alloy with great application prospects. In terms of flame-retardant titanium alloys, the Northwest Nonferrous Institute has developed a low-cost Ti40 flame-retardant titanium alloy with Chinese characteristics. Ti-V-Cr series full beta titanium alloy composed of Ti-V-Cr series Ti-25V-15Cr-0.2Si high alloying has good anti-extinguishing performance and high temperature performance. Ti40 titanium alloy will be suitable for the casing and blades of the key components of the aircraft engine.
