Si or Alshowed very strong beneficial main-effect, and at the same time often exerted im-portant influence on the behaviour of other elements. In the latter respect, Si wasthe stronger of the two. The beneficial effect of Cr was marked when the Si con-tent was low (0.1-0.2%), and completely disappeared when Si was increased to0.8-1.0%. Cu behaved somewhat opposite to that of Cr. Mo promoted the benefi-cial effect of Si or Cr, although the main effect of itself alone was unbeneficial.The main effect of Ni is weak, however, it could match with Cu, Mo and Cr-Alto yield beneficial results. With regard to the two elements which were present insteel only in small amount, V was preferable to Nb. 收稿日期: 1979-02-18      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 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I2/227 [1] Wranglen, G., Corros.
