Effects of Elements N,O and Fe on Microstructure and Property of TA15 Titanium Alloy

摘要: 本文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、透射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。在微观组织上,不同杂质含量的组织形貌、结构有一定的差别。

Abstract: The effects of impure elements N,O and Fe on microstructure and property of TA15 titanium alloy were investigated by means of microscope and TEM. The results show that the increase of impurities N,O and Fe improves tensile properties of the alloy and stress rupture properties of the alloy and the microstructure depends on the impurities and their content.
