Abstract

The creep-fatigue fracture process from the small crack initiation to the subsequent propagation behavior in a 6061 aluminum alloy composite reinforced with SiC whiskers, SiCw/6061, was investigated at high temperature. It was shown that the followings are controlling mechanism in the creep-fatigue failure: (a) nucleation of small cracks, or microcracks near the interface between the whiskers and the matrix, (b) the inhibiting effect of the whiskers against the small crack growth, (c) the crack face bridging by
