Microstructural Development and Control in Liquid Phase Sintering; Processing, Structures and Properties of Cold Worked Metal Matrix Composites

摘要

This report summarizes efforts and accomplishments in the areas noted in the title. Structural analysis of Liquid Phase Sintering materials is clarified in terms of solid phase contiguity and scale; the later being predictively so. Mechanisms for structural evolution in LPS products are also explained. Mechanical processing capabilities of in situ metal matrix composites are developed and the properties obtained in them are measured and compared with theories for the same. Guidelines for developing high strength cold worked metal matrix composites are presented. (Author)
