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
