Abstract : Metal matrix composites (MMCs) have been heavily studied over the past thirty years. During that period, many proposals have been made to develop a matrix alloy that was compatible with the reinforcing phase. However, for one reason or another, the technology has continued to focus on conventional alloys and fabrication practices. Although tremendous advances have been made on composite materials, the basic technology remains similar to systems studied twenty years ago. This work represents the first new program where new alloys are being developed for graphite reinforced composites which are tailored to a novel processing technology for manufacturing corrosion resistant graphite reinforced composites....
