摘　　要：采用真空烧结方法,在不同烧结温度下制备Ti-Mo(9∶1)多孔合金,对材料的表面形貌和微观结构进行研究。结果表明,随着温度升高,样品由松散颗粒逐渐烧结形成多孔合金。高分辨透射电镜(HRTEM)观察发现,870和890℃烧结的样品中都有α相从β相中析出,同时还可以观察到β/βremain分解为β1+β2两相。随后的室温吸氢性能测试结果表明,大量β相的析出利于提高Ti-Mo样品的吸气性能。Ti and Mo powder of high purity were mixed with a ratio of 9∶ 1 and sintered in vacuum environment.In the case of the va-rious sintered temperature,microstructure and gettering properties were tested and analyzed.With the increase of sintering tempera-ture,loosed Ti and Mo particles were gradually sintered and formed porous Ti-Mo alloy.The HRTEM results revealed that α phase was precipitated from β phase in Ti-Mo matrix sintered at 870 and 890 ℃,respectively.The β1 and β2 phases were also observed because o...
