The Development Trend Of Aviation Titanium Alloy

　　With the rapid development of aviation technology and the ever-increasing requirements for national defense construction, a new generation of aircraft must meet the needs of ultra-high speed, high altitude, long endurance, and ultra-long range. Therefore, aviation titanium alloys will be developed in the direction of low cost and high performance, and at the same time, the independent research and development of new brands and the development of new processes will continue.

　　Research on Strengthening Low-Cost Aviation Titanium Alloys

　　Replacing expensive elements such as Nb, Mo, and V with common Fe elements and vigorously developing near-net-shape technology will become two key directions for reducing the cost of aerospace titanium alloy engineering applications.

　　Research on strengthening high-performance aviation titanium alloys

　　Although titanium alloys have good comprehensive properties, the existing aviation titanium alloys still cannot fully meet the high performance requirements of materials in the aviation field. At present, the actual long-term use of high-temperature titanium alloys is difficult to exceed 600 °C. The research on aviation titanium alloys above 600 °C is still in the test and pilot stage, and there is still a long way to go before large-scale development and application.

　　Strengthen the application of additive manufacturing in aviation titanium alloys

　　The research and application of additive manufacturing technology of aviation titanium alloy will open up a new advanced manufacturing method for aviation titanium alloy processing and forming.
