Effect of Friction Stir Processing on Properties of Titanium Alloy for Automobile

The microstructure,mechanical properties and wear resistance of automotive titanium alloy at different friction stir processing parameters were studied.The results show that compared with those of titanium alloy before friction stir processing,the crystalline grains of the automobile titanium alloy after friction stir processing is finer and more uniform,and its tensile strength,yield strength increases,elongation after fracture decreases,with mechanical properties and wear resistance of the alloy improved.
