Abstract: The microstructure evolution of TA15 titanium alloy during hot power spinning was studied. Effects of wall reduction on microstructure evolution of TA15 titanium alloy were researched. Slip deformation is the main deformation mechanism accompanying with twinning to coordinate the deformation. The microstructure gradually transforms into fine fibrous microstructure and the aspect ratio of primary α grain increases with increasing wall reduction. The recrystallization fraction and microhardness increase with increasing reduction.
