Production of Magnesium Matrix Composite and the Corresponding Mechanical Properties: A Review

Abstract

In this article we question the influence of the production method on the microstructure and mechanical properties of magnesium particulate reinforced composite. Magnesium matrix composite could be produced using either of the four methods discussed in this article such as ultrasonic vibration, powder metallurgy, stir casting and Shear compaction processing. The microstructural properties of the resulting composite benefited greatly from further processing when producing the composite through liquid metallurgy rout like stir casting method. The choice of ceramic reinforcement like Silicon carbide significantly improved the mechanical properties such as hardness, tensile strength but had negative effect on the ductility of the developed composite.
