Ti3Al PHASE PRECIPITATION DURING VIBRATION FATIGUING FOR A TITANIUM ALLOY
（Institute of Aeronautical Materials; Beijing 100095）
Abstract:Ti3Al phase was dispersely precipitated in the α phase during vibration fatiguing for the Widmannstatten,basket-weave and equiaxed structures in a titanium alloy (Ti-6Al-2.5Mo-2Cr-0. 5Fe-0. 3Si), which leads to decrease the fatigue life.There is a definite orientation relationship betweenαand Ti3Al:{0001}_α {0001}Ti3Al and Ti3Al
Key words: vibration fatigue phase precipitation titamium alloy
