Mechanical Properties of Copper-TiC In Situ Metal Matrix Composite

Abstract

Copper based TiC reinforced in-situ metal matrix composite was synthesized by melting copper, hexaflurotitanate and graphite powder in appropriate proportion at a temperature of 1100 °C using stir casting technique. Both copper matrix and copper-TiC composite were subjected to microstructure studies, x-ray diffraction analysis, hardness and tensile test. Optical micrograph shows fine and uniform distribution of TiC particles throughout the matrix. X-ray diffraction analysis confirms the formation of Titanium carbide particles. Developed composite exhibit a significant improvement in hardness and ultimate tensile strength compared with unreinforced copper.
