摘要(Abstract)：

在两相区和单相区温度范围内对TA10钛合金进行了退火处理，采用扫描电镜、X射线衍射仪、电子背散射衍射和万能试验机等研究了合金经不同温度退火处理后的显微组织、织构和力学性能，分析退火温度对其组织及性能的影响机理。结果表明：退火温度会对TA10钛合金组织及类型产生显著影响；随着退火温度的升高，TA10钛合金的微观组织发生显著转变，表现为初生α相持续减少并最终消失，针状α相明显增加，组织中的主要相变过程为β→α相，最终组织中的物相以α相为主；退火温度从两相区升高至单相区，合金的{0001}晶面的混合织构特征转变为单一织构特征，强度呈现显著上升趋势，伸长率显著降低，断口形貌由韧性断裂特征向脆性断裂特征转变。

关键词(KeyWords)： TA10钛合金;微观组织;拉伸性能;断口形貌
