The heat treatment of SP-700 titanium alloy was studied to improve the property of homemade SP-700 titanium alloy. By using different solutions and aging temperatures as well as aging time, the effects of heat treatment process on microstructure and properties of SP-700 titanium alloy were systematically studied. The results show that the alloy strength increases with solid solution temperature due to the fact that the number of secondary α increases. To control aging temperature and aging time can control the shape and size secondary α, to obtain the optimum combination of strength with plasticity. Solution treating at 850 ℃, cooling to room temperature by water, and then aging at 510 ℃ or 550 ℃ will help the alloy to obtain the optimum combination of strength with plasticity.
