Abstract
Effect of boron carbide particle size and volume fraction of reinforcement on fractography of PM processed Titanium matrix composites was investigated. Pressureless sintering process was established to synthesize Titanium matrix composites. Ti-B4C powder mix was consolidated and pressureless sintered to produce in-situ TiB-TiC reinforcements in titanium matrix. Scanning Electron Microscopic studies revealed presence of TiB needles and TiC particles. The composite exhibited improved flexural strength over the unreinforced titanium processed under similar conditions due to the presence of needle shaped reinforcements.
