Due to the characteristics of low density and high temperature strength of titanium aluminum alloy, the application of C-T-i Al alloy in automotive materials has also attracted people's attention. The C-T-iAl alloy exhaust valve has successfully passed the harsh long-cycle engine test. At the end of 1997, the turbine impeller cover disk and air seal ring made of single-phase C-T-i Al alloy passed the engineering demonstration. The main applications of titanium aluminum alloy in advanced jet turbine engines are:

(1) The specific rigidity of titanium aluminum alloy is about 50% higher than that of commonly used engine materials. It can be used to make parts for frames, seal supports, casings, partitions, turbine blades and nozzle areas.

(2) Titanium aluminum alloy has good creep resistance in 600~750e, which can partially replace high-density nickel-based alloy.

(3) Good anti-combustion performance makes it possible for titanium aluminum alloy to replace the dense and expensive titanium-based flame retardant alloy.

The United States has trial-produced some jet engine parts, such as frames, seal brackets, impeller blades and partitions such as frames, seal brackets, impeller blades, and baffles. The new generation of space shuttle (x-30) has used titanium aluminum alloy as a candidate material for engine components, brackets and skins. NASA will build a supersonic single aircraft orbital transportation vehicle. Titanium aluminum alloy is one of them Important materials. It is predicted that titanium aluminum alloy will be used in high-speed flight transport aircraft (HSCT), single-stage orbit (SSTO) spacecraft (RLV) in the future, and the application of CTi Al alloy sheet in thermal structure and thermal protection system has been incorporated into future European air transport Research Program (FESTIP).

In addition to applications in the aerospace and automotive industries, the use of titanium aluminum alloys in the chemical industry, biomedical materials (such as human hip replacements), offshore industries, and energy industries has also gradually increased. In addition, the demand for titanium and aluminum alloys in the field of sporting goods and daily consumer goods (such as golf clubs, bicycles, jewelry, etc.) is also increasing, and has become a part of people's daily life. In short, due to the excellent performance of titanium aluminum alloy, its application and development prospects are broad.
