The deleterious effects due to surface enrichment of As and Cu and the oxidation at austenite grain boundaries appear to be the main cause of hot shortness of the material. 收稿日期: 1978-03-18      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 刘富有 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1978/V14/I3/310 [1] Menter, J.
