C. conditions has been carried out by SEM. The electrode potentials on fracture or polished surface of the RE free steels have been determined, and further investigations on their fractures have also been made by AES and ion-probe analysis.It was found that no intergranular fracture occurs in all the specimens ruptured at room temperature till—100℃. Most of the fractures are brittle cleavage in nature, except that a little ductile fracture appeared on fractures of the specimens ruptured at the interval from room temperature to—25℃. It seems that the cleavage fractures are enriched with phosphorus. 收稿日期: 1981-03-18      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 戢景文 李茂华 肖连芳 高怀荪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I3/293 [1] Szczepanski, M.
