本文介绍了在高温和不同的稳定应力条件下进行蠕变试验的试样的金相检验结果。讨论了微裂纹或空洞的生长与最终破裂方式之间的相互作用。一些商业合金的施加应力与断裂寿命特性的简单表达式一起被示出来描述近似的应力敏感性质，其断裂行为。
Resultsare presented of metallographic examinations of specimens which have been creep tested at high temperatures and under different conditions of steady applied stress. The interaction between the growth of micro-fissures or voids and the mode of final rupture is discussed. The applied-stress versus rupture-life characteristics of a number of commercial alloys are presented together with simple expressions which are shown to describe approximately the stress-sensitive nature of their rupture behaviour.
