It was shown that its stress-rupture life is considerably reduced by the temperature cycle. The extent of reduction is depended on the amplitude of the cycle. The formulation of life prediction for specified program-controlled temperature cycle is proposed. The fracture surface of the superalloy has also been observed by SEM. 收稿日期: 1984-04-18      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 肖耀天 佟素琴 许志显 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I4/266 1 Robinson, E.
