It is found that the thermal stability of metallic glasses composed by the preceding transition metals, e.g. Hf, Ta, W and Re is increased obviously, hut by the later ones, e.g. Os, Ir, Pt, Ru and Rh, much less influenced. These behaviour has been discussed by the Gaskell's model and Engel-Brewer electron theory of transition metals. 收稿日期: 1983-05-18      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 宁远涛 郑云 祁更新 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I5/133 1 Donald, I.
