1) Output

Although China is a big country in titanium industry, the quantity of high-quality products is not high and the types of titanium products with special properties are few. Secondly, China is not able to produce titanium strips and titanium extruded profiles in batch and stable, which limits the development and utilization of titanium and titanium alloys in aerospace, Marine and other fields. It is still very difficult to further increase the titanium consumption of aeroengines to about 50%.

2) Performance

Because titanium metal has high chemical activity, easy to be polluted by other elements, so the processing and manufacturing process of titanium alloy is very high, at the same time, the processing of high performance products need and comprehensive consideration of its mechanical, physical, chemical, technological properties, the existing titanium alloy above 600 degree , Creep resistance and the sharp decline of oxidation resistance at high temperature are the two main obstacles limiting the expansion of application of titanium alloy.

3) Cost

At present, the main application field of titanium alloy is aerospace and other military industrial sectors. The development of new application fields, such as automobiles, trains, high-speed rail, and civilian areas commonly used in daily life are still very broad application prospects. In addition, replacing expensive alloy elements with cheaper elements and reducing the cost of titanium alloy parts by technological means is an important topic in the future titanium alloy research work. Titanium alloys for high-end applications will be used in various fields in the future when they can be manufactured at a low cost.
