摘要(Abstract)：

首先对Ti650钛合金棒材进行了910～940℃低温区轧制处理，随后进行了固溶及时效处理，采用金相显微镜、电子背散射衍射技术和拉伸试验等研究了合金轧态及热处理态的显微组织、晶体取向、织构和力学性能。结果表明：低温区轧制态Ti650合金组织为α相沿轧制方向被拉长的变形组织，不同轧制温度下组织差异不明显，晶体取向以<0001>为主，织构类型主要为■织构；热处理后Ti650合金的组织经历回复和再结晶，晶粒表现出无明显择优取向，并且随轧制温度升高，织构类型不断变化；在930℃轧制时，Ti650合金的织构密度最高，为12.03,织构类型为(0001)[0011]织构，合金的屈服强度(1057 MPa)及塑性(11.9%)匹配最佳。
