The texture evolution mechanism of TA2 pure titanium under different stress (tensile stress, compressive stress) was studied by tensile and compressive test methods, combined with Schmid factor calculation and crystal plasticity simulation calculation. The results show that, in the process of tensile deformation, it is difficult to change the texture under large strain variables, while in the process of compression deformation, the texture changes is significant. Under different strain paths, there are some differences in the starting deformation mode. Under different strain variables, with the increase of deformation, the increase of grain number of base plane slip or conical slip or {10-12} stretched twin is the main reason for the formation of different textures.
