The σ and Laves phases were suppressed, and the microstructural stability increased with decreasing Cr and Si contents.The extracting process of G-phase by electrolytic and chemical method has been studied. By means of chemical in combination with electron probe analysis, the composition of G-phase was ascertained to be about Ni_(18)Ti_(10)Si_(16). 收稿日期: 1978-04-18      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 郭建亭 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1978/V14/I4/348 [1] 铁基高温合金研究组,金属学报,14(1978) ,227． [2] Speich, G.
