Because titanium alloy coil has the characteristics of low density, high temperature strength, so the application of titanium alloy coil in automobile materials has attracted people's attention. The titanium exhaust valve has successfully passed the harsh long - cycle engine tests. At the end of 1997, the turbine impeller cover plate and air seal ring made of single phase titanium alloy passed the engineering demonstration. The main applications of titanium coil in advanced jet turbine engines are:
(1) The specific stiffness of titanium coil is about 50% higher than that of common engine materials, which can be used to make parts of frame, sealing support, casing, bulkhead, turbine blade and nozzle area.
(2) Titanium alloy coil has good creep resistance in 600~750e, which can partially replace high density nickel-based alloy.
(3) Good combustion resistance makes it possible for titanium alloy coil to replace dense and expensive titanium base flame retardant alloy.
Some jet engine parts, such as frames, sealing brackets, impeller plates and spacers, such as frames, sealing brackets, impeller plates and spacers, have used titanium alloy rolls as candidates for engine parts, brackets and skins. It is predicted that titanium alloy coil will be used in high-speed flight transport aircraft and single-stage spacecraft in the future. The application of titanium alloy coil in thermal structure and thermal protection system has been included in the future European air transport research program.
In addition to applications in the aerospace and automotive industries, titanium alloy coil is also increasingly used in the chemical industry, biomedical materials (such as human hip implant replacement), offshore industry, energy industry. In addition, titanium alloy rolls are increasingly in demand for sporting goods and consumer goods such as golf clubs, bicycles or jewelry, and have become a part of People's Daily life. In short, because of the excellent properties of titanium alloy coil, its application and development prospects are broad.
