The constitutions of these two systems are strikingly similar; besides a b.c.c, ternary terminal solid solution and a ternary Laves phase isomorphous with MgCu_2 structure, no new intermediate phase has been found.In the Mo-Ti-Zr system the lattice parameter of the ternary solid solution increases with the increase of Ti or Zr in solid solution, and the ternary Laves phase is (Ti, Zr) Mo_2. In the Mo-Nb-Zr system, the lattice parameter of the ternary solid solution also increases with the increase in the Nb- or Zr-content, and the ternary phase in this case is Zr(Mo, Nb)_2.The iso-hardness contours of the Mo-Ti-Zr system tend to expand towards the titanium corner as the Ti-content is increased, whereas those of the Mo-Nb-Zr system expand towards the niobium corner with the increase in Nb-content in a like manner. 收稿日期: 1966-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 庄育智 唐全红 庄祥麟 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1966/V9/I1/63 [1] Hansen, M., Kamen, E.
