One is called the "blocky" band with discrete α-Mo particles, and the other is the "white" band without α-Mo fibre. Both bands seriously deteriorate the mechanical properties of the alloys. By using the glow discharge emission spectroscopy, the chemical composition of band structures was analyzed layer by layer. Based on the composition variation and constitutional supercooling theory, the cause of band formation has also been discussed. 收稿日期: 1984-02-18      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 张玉生 于洋 唐亚俊 张静华 王素坤 胡壮麒 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I2/118 1 Carruthers, J.
