英文摘要	Influences of applied shear stress on the nucleation process and micro-texture formation of alpha precipitates, beta ->alpha transformation in Ti-6Al-4V alloy were simulated by phase field method with Pandat software and JmatPro (TTT-Ti) databases as direct input in the model. The effects of applied positive and negative shear stresses (10, 30 and 50 MPa) along (101) [(1) over bar 11](beta) or (12 $$(1) over bar) [(1) over bar 11](beta) on the microstructure evolution of Ti-6Al-4V alloy were explored at certain aging temperature. The results show that with the increase of shear stress, the elastic interaction between applied stress and a variants gradually plays more significant role in determining the microstructure of the system under certain undercooling; therefore, the selection of alpha variants is gradually enhanced. It is found that the shear stress has a stronger effect on the variant selection than the normal stress, and thus it may be more effective in microtexture formation. With the increase of shear stress, two or one type of variant are selected under positive shear, and one type of variant is favored by the negative shear along (101) [(1) over bar 11](beta) or (12 $$(1) over bar) [(1) over bar 11](beta).
