摘要
本文通过对喷丸、渗氮及碳氮共渗试样疲劳行为的研究,提出了金属内部疲劳极限的概念,指出内部疲劳极限约为表面疲劳极限(一般意义上的疲劳极限)的1.35倍。
An aspect of the intermal fatigue limit for metals was proposed with the aid ofappraisal of the fatigue behaviour of shot peened, nitrided or carbonitrided steels. The inter-nal fatigue limit of metals seems to be 1.35 times of surface one. Based on this aspect, the fa-tigue strength of surface hardened steels was analysed.
