In situ reacted titanium carbide-reinforced aluminum alloys composite

An aluminum matrix containing titanium carbide particles was fabricated by in situ process in which a carbonaceous gas reacts with titanium in a liquid melt to form TiC. The tensile and yield strength increased by up to 18% after the formation of TiC in the Al alloy matrix. The hardness increased by up to 20%. The abrasive and sliding wear resistance increased with the in situ formation of TiC particles.
