Abstract

The literature reviewed in this paper on rapid solidification processing techniques for discontinuously-reinforced metal matrix composites presents a cross-section of techniques and experimental results obtained, in recent years, by numerous investigators. The results, documented by researchers, from both academia and industry, have enriched our understanding of the interrelationships between processing-microstructural characteristics and macroscopic behavior, and suggest the existence of a potential for rapid improvement in processing techniques in the years to come. The primary limitations that place constraints on the rapid advancement of the field of processing lies in the development of techniques that facilitate wettability between the metal matrix and ceramic reinforcement coupled with high speed compaction techniques that would result in minimum exposure of the composite to elevated temperatures. Although shock consolidation has emerged as a viable technique that overcomes many of the problems and shortcomings associated with thermal compaction processes, it is limited by its ability to control the homogeneous distribution of the shock wave during consolidation.
