摘　　要：主要研究了杂质元素N、O、Fe含量对TA15钛合金力学性能的影响,并通过光学显微镜、扫描电镜等实验手段对不同杂质成分的微观组织进行了研究分析。研究结果表明：随着杂质N、O、Fe含量的增加,TA15钛合金的室温拉伸、高温持久均得到提高。在显微组织上,不同杂质含量的组织形貌、结构有一定的差别。This paper studied the effects of contents of impurity elements nitrogen, oxygen and iron on mechanical properties of TA15 titanium alloy. It also studied the microstructures of TA15 titanium alloy with different contents of impurity elements under optical microscope and scanning - type electron microscope. The results showed that the room - temperature tensile strength and high temperature stress rupture of TA15 titanium alloy enhanced with the increase of impurity elements nitrogen, oxygen and iron. There was some difference between microstructures with different contents of impurity elements.
