Results obtained on certain commercial as well as experimental heats sustained its usefulness. The formula:△N′_V= Ni-3Ti-3.5A1-1.7Si-0.9Cr-4.7 has been found to be useful in predicting the conditions with regard to the formation of σ-phase of a 25Ni-15Cr type alloy as an example. When △N_V>0, the alloy remained σ-free after prolonged exposure at 650℃. 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 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1978/V14/I4/440 [1] Beattie, H.
