Under the examination of atomic properties of these elements, it seems to be drawn that the electron concentration is the chief controlling factor for the a-Ti_3X-phase boundary. The investigation was made with four selected ternary alloy systems: Ti-Al-Ga, Ti-Al-Sn, Ti-Al-Zr and Ti-Al-O. The experimental resuits show that the formation of Ti_3X-phase obeys the electron concentration rule, and the valence electron number of the alloying elements depends on their own electronic structures, i.e., N_(Ti)=N_(Zr)=2 for the transition elements Ti and Zr; N_(Al)=N_(Ga)=3(S~2P~1), N_(Sn)=4(S~2P~2) and N_o=6(S~2P~4) for non-transition elements Al, Ga, Sn and O. The characteristic electron concentration for the formation of Ti_3X-phase may be expressed as: 收稿日期: 1984-06-18      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 李东 刘羽寅 万晓景 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I6/375 1 Blackburn, M.
