The fracture and the surface of a hip joint fractured invivo has been studied by SEM. It is concluded that the fracture was due to corrosion fatigue cracking by bending stress.
利用SEM对实际使用时断裂的髋关节的断口和表面进行了分析，认为此关节的断裂为以弯曲应力为主的腐蚀疲劳断裂。
There are some factors which influence the characteristics of initiation and propagation of stress corrosion cracking and corrosion fatigue cracking in high-strength steel in a watery environment.
影响高强度钢在水介质中的应力腐蚀和腐蚀疲劳裂缝萌生和扩展特性的因素甚多。
Through-thickness cracking also can lead to fatigue or stress corrosion cracking of the base metal beneath the plating.
还会形成穿透型裂纹，造成镀层下本体金属的疲劳或应力腐蚀裂纹。
