Special attention is given on the mechanical pro-perties of three varieties of this new material. Owing to its certain distinguish-ing properties, this nodular cast iron has found a wide-spread application inChina. 收稿日期: 1977-04-18      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 罗干 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1977/V13/I4/320 No related articles found!
