Synthesis and Characterization of Nano-Glass Particles Reinforced AZ91D Magnesium Alloy Composites

In the present study, a considerable importance is being given to find a novel material for marine application. The synthesis of nano-particles reinforced with matrix alloy using conventional casting offers low wettability between reinforcement and the molten metal. Hence, an effort has been made to develop nano-glass particles reinforced magnesium alloy matrix to enhance the wettability between the matrix and the reinforcement. The die cast magnesium unified with various mass fractions percentage of nano-glass particles of particle size 30 µm has been synthesized using stir casting method. The influence of nano-reinforcement on micro structure and mechanical properties of developed nano-composites have been analyzed. From the experimental results, it has been inferred that synthesized composites have homogeneous grain structure, low density, minimal porosity, and excellent matrix-reinforcement interfacial integrity. The main interfacial phase has been identified as Mg₁₇Al₁₂ between the reinforcement and matrix alloy.
