| Abstract: | 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. |
