Abstract

Fatigue was examined for three commercially fabricated aluminum matrix composites containing SiC whiskers and particles under rotating bending in laboratory air. Fatigue strength at 10⁷ was about 67% higher for the composite than that for the matrix alloy. SiC_p/A356 and SiC_p/A357 composites the fatigue strengths were also higher than that of the matrix alloy. Fractography revealed that a mode II crack propagated through the whisker/matrix or particle/matrix interface for SiC_w/A2024 and SiC_p/A357 composite materials. For SiC_p/A356 composite material, the crack initiated at some small voids beneath the surface. Mode I and Mode II fatigue crack propagation models are proposed.
