Research on engineering application of low cost titanium alloy in vehicle fields
With the increasing use of titanium alloys in aerospace and other fields,expensive processing and use costs have become the main obstacles restricting their expansion and application.It is urgent to develop low-cost titanium alloy materials and their processing technologies.Therefore,the low cost of titanium alloys and the low cost of titanium alloy material forming have become an important research direction in the field of titanium industry at home and abroad.In this paper,Ti-Al-V series low-cost ti-tanium alloy ingots with qualified chemical composition were successfully prepared by adding 100%re-turn material,and various specifications of plates were prepared by short process rolling technology.The evolution process of microstructure and properties of Ti-Al-V series low-cost titanium alloy during rolling process was analyzed.The developed plates of various specifications passed the assessment test of a vehicle turret body.At the same time,a low cost and high performance titanium alloy balance el-bow forging was developed by using short process forging technology.Its microstructures and mechani-cal properties can meet the requirements of technical standards,and passed the test of a vehicle.
