Results show that the formation ofTi_3X-phase in the Ti-Al solid solution containing the transition elements Sc, V, Nb or Mo obeys the electron concentration rule as well, and the valence electron number of the transition elements depends on the structures of their d energy bands, i.e., N(Sc)=2(S~2) for the elements, e.g. Sc, on the left of Ti in the periodic table; N_v=3(d~3), N_(Nb)=4(d~4) and N_(Mo)=5(d~5) for the elements V, Nb and Mo on the right of Ti, respectively. Furthermore, it seems that the formation of Ti_3X-phase could not be'restrained by an addition of any transition element to the alloy. 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 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I6/384 1 李东;刘羽寅;万晓景,金属学报,20(1984) ,A375．屯屯屯屯屯 No related articles found!
