Continuous SiC fiber reinforced aluminum (Al-SiC[sub f]) composites generally have very high elastic modulus and strength combined with light weight, providing potential aerospace applications. In order to develop better composite materials with improved mechanical properties, however, a fundamental understanding of the relationship between microstructure and the mechanisms of deformation and failure is essential. A number of studies have been reported concerning the mechanical properties of Al-SiC[sub f] composites, and the recent studies have emphasized the importance of the interface between matrix and fibers since the presence of brittle reaction products at the interface can seriously degrade mechanical properties. There is, however, only limited information available on the effect of carbon-rich coating layer, which covers the fiber surface, on the fracture process of the Al-SiC[sub f] composites. Thus the principal objective of this study is to elucidate a more fundamental understanding of how the microfracture process is affected by microstructure and processing methods in a 6061 aluminum alloy composite reinforced with SiC fibers. Particular emphasis has been placed on studying in detail a mechanism of microfracture process at a blunt notch tip using an in situ fracture technique.
