Processing SiC-particulate reinforced titanium-based metal matrix composites by shock wave consolidation

Abstract

SiC particulate reinforced titanium matrix composites have been processed by shock wave consolidation. These materials are difficult to produce using traditional methods because of the high reactivity of titanium with most reinforcement materials. However, using shock consolidation, fully dense composite compacts that are free from interfacial reactions and macroscopic cracks have been obtained. Process variables (starting powder size, dispersion of SiC particles, chemical impurity level, and pre-compaction degassing and heat treatment) have been investigated. Proper post-consolidation annealing has also been explored to improve impurity segregation and, thus, ductility of the matrix. Subsequent heat treatments of the composites produce controlled interfacial reaction zones sizes. The processed materials are ideal for studying effects of interfacial properties on the mechanical behavior of particulate reinforced metal matrix composites.
