摘要
用扫描电镜和光学金相研究了ＬＣ４铝合金疲劳试件的宏、微观断裂特征，论述了试件断裂位置转移和疲劳寿命分散的原因，讨论了加工与装配质量对疲劳寿命的影响。
his paper studies the macromicro-fractog-rpohic characheristic of LC4 aluminium alloy fatigue ele-ments by means of SEM and optical metallograph. The cause of the fracture position transference and of the fatigue life scatter is diseued.The influences of processing and installing quality on the fatigue life are also investigated.
