With the development of society,the production and consumption of cars grows sharply.However,this brings problems of fuel consumption,environmental disruption and potentially safety hazard at the same time when it brings convenience to people.According to statistics,60% of the fuel that combusted by car is for the vehicle weight itself.That is to say,every 10% reduction ofthe weight of cars means10% reduction of exhaust gas and 7% for fuel consumption.

Nowadays,the light alloy that uesd by automobile are aluminum,magnesium and titanium etc.The specific strength of titanium alloy is higher than aluminum and steel,while ductility is almost the same and corrosion-resistance is much better than steel,Cryogenic titanium alloy can still keep good plasticity at -253℃.The working temperature for heat-resistant titanium alloy can reach to 550℃;while still possess good machinability,welding properties.The usage amount of titanium parts is in creasing continually and is was about 3000 tons/year in 2009.Although there were no specific data in 2012,but it would not less than 4000 tons/year.So it can be seen that the application of titanium material in automobile industry has come to the accelerating stage.
