| 摘 要： | Ｚｒ－Ｍｎ－Ｖ－Ｎｉ合金中Ｚｒ－Ｎｉ金属间化合物与Ｌａｖｅｓ相共存，Ｚｒ０．５Ｔｉ０．５Ｍｎ０．２Ｖ０．６Ｎｉ１．２合金内形成了含Ｔｉ的ｂｃｃ相，选区电子衍射和ＥＤＳ能谱分析结果表明，ｂｃｃ相为Ｂ２型Ｒ相（Ｔｉ０．５Ｚｒ０．２）Ｎｉ，Ｔｉ取代部分Ｚｒ，改变了四元合金中Ｌａｖｅｓ相的晶胞参数和亚结构，非Ｌａｖｅｓ相的形成导致合金元素在各相间的重新分配，多相合金内Ｌａｖｅｓ相的晶胞参数合金的名义成分。

| Abstract: | The Zr-Ni intermetallic compounds coexist with Laves phase in the Zr-Mn-V-Ni alloy. Zr0.5Ti0.5Mn0.2Vo.6Ni1.2 alloy accommodates C14 Laves phase and Ti containing bcc phase. Selected area electron diffraction (SAED) and energy dispersive spectrum (EDS) analysis show the bcc phase was B2 type R phase (Ti0.8Zr0.2)Ni. The lattice parameters and substructure of Laves phase in ZrMn0.2V0.6Ni1.2 alloy varied after Ti substitution for Zr. Formation of non-Laves phases causes the alloying elements redistribution among the coexisting phases. The change of electrochemical properties of Zr0.5Ti0.5Mn0.2V0.6Ni1.2 can be attributed to the Ti substitution for Zr site in C14 laves phase, the formation of (Ti0.8Zr8.2)Ni phase and disappearance of Zr-Ni binarg compound. |
