| 摘 要： | 以粉末冶金及金属压力加工方法制备了掺Ｌａ２Ｏ３钼丝和纯钼丝，采用金相显微镜、Ｘ射线衍射、电子拉伸机、扫描电镜及能谱分析等手段，对上述２种坯料及其不同温度退火后的丝材作了研究，结果表明，掺Ｌａ２Ｏ３改善了坯料的组织性能；掺Ｌ３２Ｏ３钼丝中的第二相主要是Ｌａ２Ｏ３粒子，它能显著改善钼丝的强韧性能。

| Abstract: | Wires of molybdenum doped with lanthanum oxide(LM)have been prepared usingpowder metallurgy and metal working methods.The microstructures and properties are in-vestigated by using X-ray diffraction method, optical microscope,SEM,multifunctionalelectronic terision tester and are compared with those of pure molybdenum wire(PM).It isshown that La2O3 can improve properties of molybdenum wire remarkably.The final struc-ture obtained consists of an interlocked microstructure with large aspect ratio. |
