Effect of particle inclusions on the mechanical properties of composites fabricated by liquid metallurgy

Abstract

Metal Matrix composites refer to a family of metal-based materials reinforced with fiber, whisker or particulate, which can produce considerable alteration in the physical and mechanical properties of the base alloy. The present work investigates the influence of particle additions in the basic properties of the composite. Adding dispersoids such as quartz, magnesium and silicon carbide to the matrix increases their strength and hardness. Wear resistance is found to increase with increase in percentage composition. Microstructural examination of the specimens shows fairly uniform distribution of the dispersoids.
