Research Progress of High-temperature Titanium Alloys

As an important material for aero engines, high-temperature titanium alloys are mainly used to manufacture compressor discs, fans, blades, casings and connecting rings and other components of aero engines, which is a hot spot in the research field of titanium alloys. The thermal stability, creep performance and oxidation resistance are effective indicators to evaluate the high-temperature properties of alloys. At present, a large number of studies have been carried out for high-temperature titanium alloys, but these studies are relatively scattered, systematic, and less comprehensive. The research progress of high-temperature titanium alloys in recent years was systematically summarized, and the research status of thermal stability, creep properties and oxidation resistance of α+β and near-α super-titanium alloys was expounded. The basic methods for improving the performance of high-temperature titanium alloys were sorted out and proposed to provide a technical reference for the preparation of super-temperature titanium alloys with better performance.
