摘要	ABS T R A C T Mo element significantly affects the microtexture evolution of alpha in alpha + beta titanium alloys. In this study, the evolution of microtexture during thermomechanical processing in Ti-6Al-2Sn-4Zr-2Mo (Ti6242) and Ti-6Al-2Sn-4Zr-6Mo (Ti6246) alloy was investigated. The beta annealing treatments and alpha + beta solution-treatments were con-ducted to display the microstructure characteristics before thermal deformation. Then, the thermal compression in the (alpha + beta) phase region was applied to trace the evolution of lamellae orientation in conjunction with the electron backscatter diffraction. The results show a strong prior colony microtexture before thermal deformation. {10-12} and {10-11} twins are activated in Ti6246 during thermal compression, which strongly weakens the microtexture of the prior alpha colony. Besides, the lower volume fraction of the primary alpha phase, the smaller alpha colony, the thinner lamellae and the lower aspect ratio of alpha grains contribute to weak prior colony microtexture in Ti6246 alloy. This study shows the effect of Mo content on the microtexture evolution during thermo-mechanical processing.
