摘要:
通过对某机右中外翼开裂不壁板裂纹源区材料的扫描电子显微镜分析，发现金相照片上有应力腐蚀、疲劳破坏的显著特征，从而得出结论，其疲劳开裂模式为由应力腐蚀诱发的腐蚀波劳开裂。
Abstract:
Mter an analysis of the crack - source material of the cracked down skin of the right-middle-outer wing in an aircraft by means of the electron scanning microscope , a lot of features known as corrosion , stress corrosion and fatigue damage have heen detected in the photomicrograph. Thus the conchrsion can he drawn that the crack mode of the cracked down skin is of corrosive fatigue cracking caused hy stress corrosion.
