摘要: 本文应用电子断口学、断裂力学的方法,通过实际断裂构件的分析和腐蚀疲劳(CF)、应力腐蚀开裂(SCC)实验,观察到钢在CF条件下裂纹扩展形态不是单一的.它与钢的临界应力强度因子K_(IC),临界SCC强度因子K_(ISCC),CF最大应力强度因子K_(Imax),应力强度因子范围△K,应力比R及频率f等有关.当dK/da>0时,基本的断裂形态有三种:(1)当K_(Imax)
Abstract:Through the analysis of parts failed in service by electronfractography andfracture mechanics, and by corrosion fatigue (CF) and stress corrosion cracking(SCC) experiments, it was shown that under the condition of CF,the crackingmorphology of steel is not merely governed by a single mechanism. It dependsupon the critical stress intensity factor of the steel K_(IC), CF maximum stress in-tensity factor K_(Imax), threshold SCC intensity factor range △K, frequency f, stressratio R, etc. In case of (dK/da)>0, three basic fracture morphologies wereobserved: (a) when K_(Imax)
