TC16钛合金在780、800、850、900℃下固溶热处理30 min,分别以水淬、空冷、炉冷方式进行冷却,再分别在520、560和600℃保温2、4、8、16 h空冷进行时效处理,利用OM和室温拉伸性能测试等方法,研究了不同热处理工艺对TC16钛合金棒材组织和性能的影响。结果表明,固溶温度对TC16钛合金塑性影响不大,相同的固溶时效处理制度下,随时效时间增加和温度的提高,合金强度和塑性都增加。 TC16钛合金较合理的固溶时效处理工艺为：(780±20)℃固溶处理,保温2 h,炉冷至550℃以下后空冷,后在560℃下时效8 h,空冷,如此能获得要求的室温拉伸性能及良好的综合性能。

The effect of solution treatment on microstructure and properties of TC16 titanium alloy with solid solution treatment at 780, 800, 850, 900 ℃ for 30 min, then cooled by water air, and in furnace and aging at 520, 560 and 600 ℃ for 2, 4, 8, 16 h air cooling respectively were studied by OM and tensile test at room temperature. The results show that the effect of solid solution temperature on the plasticity of TC16 titanium alloy is not obvious under same solid solution and aging condition, with the increase of the aging time and rise of the temperature, the strength and plasticity of the alloy are increased. The solid solution and aging of TC16 titanium alloy is more reasonable way:solid solution at (780 ± 20) ℃ for 2 h, furnace cooling to below 550℃ and air cooling, aging treatment at 560℃ for 8 h, air cooling, the desired tensile properties at room temperature and good comprehensive performance can be obtained.
