The SCC was observed on them after 110, 73—100 or 262—324 h respectively. Their fracture surface are charaterized by the stratified rock structure and the striation-like pattern of quasi-cleavage rather than the river marks or the fan pattern under the tensile stress. Almost one order of magnitude of the incubation period of SCC under the compressive stress is prolonged beyond that under tension. Because the cracking propagates very slowly and spreads hardly to distinguish, the SCC under compressive stress does not be revealed, if it is under tensile stress simultaneously. The behaviour of hydrogen in SCC of such system has been also discussed. 收稿日期: 1983-05-18      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 姚京 褚武扬 肖纪美 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I5/81 1 Brown, B.
