Innovative Processing Techniques for Intermetallic Matrix Composites

Abstract

AbstractAlthough intermetallics based upon aluminum or silicon tend to have a very attractive combination of low density and excellent oxidation resistance, they suffer from lack of adequate creep strength and, in most cases, from inadequate ductility and toughness. It has been recognized for several years that an approach which could simultaneously solve both problems, without degrading other properties, is to utilize the intermetallics as matrices for composite materials. The consequence has been an explosion of interest in two-phase intermetallicbased alloys, as is manifested in the current symposium.
