the Laves-phase alloys Zr 1 − x Ti x (Mn 1 − y V y ) 2 , have been studied by X-ray powder diffraction and transmission electron microscopy (TEM). Hydriding properties were analyzed from pressure-composition (PC) isotherms. Most of the alloys were multiphase, with up to four phases simultaneously present in one alloy. The identified phases were: hexagonal C14 and cubic C15 Laves phases, bcc solid solution
摘要 通过 X 射线粉末衍射和透射电子显微镜 (TEM) 研究了 Laves 相合金 Zr 1 - x Ti x (Mn 1 - y V y ) 2 的晶体结构和形貌。从压力组成 (PC) 等温线分析氢化性能。大多数合金是多相的,一种合金中同时存在多达四个相。确定的相是:六方 C14 和立方 C15 Laves 相、bcc 固溶体、α -ZrO 2 和 η-碳化物型氧化物。构建了系统的定性相图。TEM 测量表明 Laves 相 C14 和 bcc 固溶体具有优先原子组成。为了阐明该结果,制备合金 Zr 0.6 Ti 0.4 Mn 1.1 V 0.9 和 Ti 0.2 Mn 0.2 V 0.6 并通过 X 射线粉末衍射进行分析。
