摘 要: 探索β稳定元素Mo对600 ℃高温钛合金组织和性能的影响。结果表明,加入一定量β稳定元素Mo的Ti60合金综合性能优良,具有较优的热强性、工艺塑性和热稳定性。但过量的Mo会在βT内偏聚,使得Al更多地固溶于α相中,影响合金工艺塑性和热稳定等性能。不含Mo的Ti60合金因得不到复合强化,合金的室温和600 ℃高温拉伸强度低。

Abstract:The effect of β stabilized element Mo on the microstructure and mechanical properties of Ti60 was discussed. The results show that high temperature titanium alloy with an appropriate amount of Mo has excellent comprehensive properties such as good hot strength, ductility and thermal stability. Due to clustering in βT excessive addition of Mo has bad influence on the alloy’s ductility and thermalstability.
