摘　　要：由于钛合金在力学性能上具有屈强比高、弹性模量小等特点,成形上表现为变形范围窄、易开裂、回弹大和尺寸精度难于保证。为克服上述钛合金成形难点,一般需将其加热到较高的温度进行成形。本文重点讨论了钛合金热成形模具的材料选择及设计,并提出了热成形模具标准化是未来的重点发展方向。Since the titanium alloy having a high yield ratio, a low elastic modulus and other characteristics on the mechanical properties, it causes narrow deformation range, easily cracking, large springback and difficulty to ensure dimension accuracy. To overcome the above difficulties, it is generally necessary for titanium alloy forming to be heated to a high temperature. the titanium alloy thermoforming mold material selection and design are focused on. It is also proposed that the standardization of thermoforming mold is the future development tendency.
