摘　　要：针对TB3钛合金生产中存在的问题,研究了热处理冷却速度对合金组织和性能的影响。结果表明,冷却速度对TB3合金性能影响不大,但水冷试样的性能稍优;经固溶处理,晶粒等轴化并进一步长大,水冷试样组织的尺寸大小及均匀性稍好于空冷试样的。The influence of cooling rate of heat treatment on microstructure and tensile properties of TB3 titanium alloy are investigated in view of the problems in the alloy production. The results show cooling rate has a little influence on tensile properties, the properties of water quenching specimen are slightly superior, and the grain tends to equiaxed and grows further due to solution treatment, but the gain size and uniformity of the water quenching specimen are slightly superiorer than that of the air-cooling specimen.
