The microstructure of Ti-1500 alloy in three deformation zones at different hot upsetting temperatures was comparatively analyzed through hot upsetting experiments. The results show that the hot upsetting process has a significant influence on the microstructure evolution, and the higher the hot upsetting temperature and the larger the deformation degree, the more obvious the regional dynamic recrystallization. Specifically, dynamic recrystallization does not occur in deformation zone Ⅰ and deformation zone Ⅱ at 700 ℃, but obvious recrystallization occurs in deformation zone Ⅲ, α→β phase transformation occurs at 820 ℃, obvious dynamic recrystallization occurs in all three deformation zones, and the recrystallized grains grow excessively at 900 ℃. During upsetting at 700 ℃, the {001}//ND texture is formed in the deformation zone Ⅰ. With the increase in deformation degree, the direction of grains in the deformation zone Ⅱ gradually changes to the directions of <001> and <111>, finally the {001} texture with higher strength and more volume fraction is formed, and a part of the {111}//ND texture is formed. When the deformation amount increases and influences the deformation zone Ⅲ, recrystallization forms new grains with <001> orientation, and the boundaries of <001> oriented grains migrate to those of <111> oriented grains, which leads to the further increase of {001} texture strength and volume fraction, while the volume fraction of {111} texture decreases. And the texture type, texture strength and texture evolution law at 820 and 900 ℃ are consistent with those at 700 ℃.
