Abstract:
It is known that thermal exposure and thermal cycling can lead to deterioration in the tensile properties of many unidirectionally reinforced metal matrix composites (MMCs). The causes of property degradation have been identified as matrix softening, fibre degradation, the generation of interfacial reaction products, and void generation(1-4). The present note indicates that thermal cycling of alpha-Al2O3/Mg alloy MMCs also has a marked effect upon the fracture toughness properties and concerns a scanning electron microscopy (SEM) investigation of this phenomenon.(author)
