Abstract: In this paper, the changes of the structure and properties of the spinning titanium cylinder were studied by keeping the titanium cylinders at 510℃, 520℃, 530℃ and 540℃ for the same time. The results show that the grain size grade and conductivity of the titanium cylinder increased first and then decreased with the increase of the temperature. At 520℃, the grain size grade reached the highest grade 12 and the conductivity reached 3.44% IACS.The hardness and tensile strength of titanium cylinder decreased with the increase of annealing temperature, the hardness decreased from 191HV in spinning state to 134HV at 540℃, and the tensile strength gradually decreased from 434MPa in spinning state to 296MPa, the elongation increased from 24.3% to 44.3%.
