摘 要: 采用Gleeble−3800热模拟机对TC16钛合金丝材分别进行冷镦、热镦实验，利用SEM、TEM、显微硬度计等手段对冷镦、热镦样品及成形后再固溶时效热处理的样品进行显微组织观察和硬度测试。结果表明：冷镦与热镦样品在显微组织和性能上存在差异，但重新固溶时效热处理后，冷镦与热镦样品的显微组织和力学性能接近。

Abstract:The effects of cold and hot upset on the microstructures and properties of TC16 titanium alloy were studied. Means of SEM , TEM and micro-hardness tester were used to analyze the microstructures and hardness of cold and hot upset samples as well as the deformed samples after solution plus aging heat treatment. The results show that although there are some differences between the cold and hot upset samples, their microstructures and properties are nearly the same after solution plus aging heat treatment.
Key words: TC16 titanium alloy; cold upset; hot upset; microstructure; property
