Magnesium Alloy – SiCp Reinforced Infiltrated Cast Composites

Abstract

This article relates to the fabrication of magnesium and magnesium alloy with SiCp reinforced metal matrix composites (MMCs) by a relatively new infiltration route. The preform for the fabrication of MMC was prepared by a mixed particle method where the matrix metal particles are mixed with the required volume percent of reinforcement without the use of any binders. Characterizations of fabricated composites were done by microstructure, microhardness, and wear studies. The studies revealed that an increase in the volume percent of reinforcement had beneficial effect on the microhardness values and wear studies.
