With the rapid development of aviation technology and the ever-increasing requirements for national defense construction, the new generation of aircraft must meet the needs of ultra-high speed, high altitude, long endurance, and ultra-long range. In order to improve the reliability of aircraft, advanced aircraft and engines have increasingly increased the amount of high-performance materials such as
titanium alloys, and their structures have become more and more complex. Therefore, aerospace titanium alloys will develop in the direction of low cost and high performance, and at the same time continue to carry out independent research and development of new grades and new process development.
Research on strengthening low cost aerospace titanium alloy titanium rods
The aerospace industry’s requirements for materials pay more attention to the balance between performance and cost, and no longer blindly pursue high performance. Low cost will run through the entire life cycle of products such as material selection, structural design, manufacturing process, testing and evaluation, and maintenance. Reducing the cost of titanium alloys has already It is an inevitable trend of industry development. Substituting common Fe elements for expensive elements such as
Nb,
Mo, and V, 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 aerospace titanium alloy
Although titanium alloys have good comprehensive properties, the existing aerospace titanium alloys still cannot fully meet the high performance requirements of materials in the aerospace field. At present, it is difficult for high-temperature titanium alloys to break through 600°C in actual long-term use. The research on aerospace titanium alloys above 600°C is still in the experimental and pilot stage, and there is still a long way to go for large-scale development and application. In addition, the batch stability research and application of flame-retardant titanium alloys, high-strength, high-toughness and damage-tolerant titanium alloys have become the focus of many scholars. Future research on high-performance aerospace titanium alloys will tend to dig deeper into existing alloys and develop new grades of alloys.
