Fabrication and Characterization of In-situ TiC Reinforced Metal Matrix Composites

Breif

Ceramic reinforced metal matrix composites have interested many researchers and used as wear resistant materials commercially. Among common reinforcing particles, titanium carbide (TiC) is a useful reinforcement ceramic system for metal matrix composites because of its stability at high temperatures, excellent hardness, wear resistance and high modulus. However, TiC reinforced metal matrix composite by addition of TiC particles in metal matrix has poor interfacial properties between the reinforcement and the matrix due to contamination by impurities during fabrication processes. In contrast, composites fabricated by in-situ reactive processes shows the formation of finer reinforcement particles and clean interfaces between reinforcement particles and the matrix since thermodynamically stable reinforcement particles form within the metal matrix. The TiC reinforced metal matrix composites can be applied to various areas, which require high hardness and wear resistance, such as roller and metallic molding equipment etc.
