Recent Research and Development of Titanium Alloys for Aviation Application in China

The output capacity of titanium sponge and mill products in China has ranked the first in the world. Compared with the developed countries,the aviation application level and amount of high performance titanium alloys in China still far lags behind that of developed countries. Based on the summary of research situation in titanium alloys technology,the technology maturity promotion approaches of new type and key titanium alloys is given by means of the optimization of synthetical properties,the variety and complete specifications,the expansion of the application scales,the sophistication of standard and specifications,the sufficiency of testing and verification,etc. And it is also very necessary to establish an aviation-oriented titanium alloys system with Chinese characteristics,to meet the design requirements of high performance,low cost,and a raised amount of consumption and application level of titanium alloys.
