Enhancing the properties of magnesium using SiC particulates in sub-micron length scale

Abstract

The microstructural, physical and mechanical properties of pure magnesium reinforced with different volume fractions of 0.6μm silicon carbide (SiC) particulates were investigated. It was found that pure magnesium were synthesized using the disintegrated melt deposition technique (DMD). It was observed that the methodology including DMD coupled with hot extrusion could be utilized to synthesize elemental and sub-micron size silicon carbide reinforced reinforced magnesium with minimal porosity. The results reveal that superior coefficient of thermal expansion (CTE), hardness, elastic moduli and 0.2% yield strength could be obtained using much lower amount of SiC particulates in sub-micron-length scale.
