摘　　要：针对TC31钛合金高筋薄腹板锻件,在α+β相区进行不同温度下的锻造试验,获得了不同锻造温度下的TC31钛合金强度和显微组织形貌,结果表明:TC31钛合金在Tβ-50℃到Tβ-20℃温度区加热锻造得到的显微组织均为α+β双态组织,拉伸性能满足技术条件要求,其中在Tβ-35℃拉伸性能最优。For TC31 titanium alloy high-reinforced thin-web forgings,forging tests at different temperatures in theα+βphase zone have been performed,and the strength and microstructure morphology of TC31 titanium alloy at different forging temperatures have been obtained.The results show that the microstructures obtained by heating and forging of TC31 titanium alloy are allα+βdual-state structures in the temperature range of Tβ-50℃to Tβ-20℃,and the tensile properties meet the technical requirements.Among them,the tensile properties are the best at Tβ-35℃.
