| 摘 要： | 为了解不同时效参数对Ti-6Al-3Nb-2Zr-Mo(Ti6321)合金组织和力学性能影响的根本原因，通过光学显微镜(OM)、扫描电镜(SEM)、透射电镜(TEM)和力学性能测试，研究了不同时效条件(500～650℃，3～24 h)下的显微组织和力学性能。结果表明，次生相α(αs)比初生相α(αp)对时效参数更为敏感。此外，αs相的厚度与时效温度和时效时间呈正相关。随着时效温度和时效时间的增加，Ti和Al元素在βt相中的偏析明显，αs相由细针状转变为长棒状。当合金在600℃时效12 h时，合金表现出较好的综合力学性能。抗拉伸强度、屈服强度和伸长率分别为907 MPa、796 MPa和16%，冲击功为55 J。
