Abstract:
In the present study, new light weight nanocomposites (AZ311.5Al 2 O 3 -Ca) based on magnesium alloy AZ31B are developed using disintegrated melt deposition technique. Microstructural characterization studies revealed equiaxed grain structure, minimal porosity, and good matrix-reinforcement interfacial integrity. The results also showed that addition of both nano-Al 2 O 3 and Ca led to a simultaneous improvement in 0.2% yield compressive strength (0.2% YCS), ultimate compressive strength (UCS), and work of fracture (WoF) of the AZ31B magnesium alloy while failure strain was slightly compromised. Moreover, excellent oxidation resistance of this composite was realized when compared to AZ31B up to 500°C. The results suggest that this composite formulation can be used in diverse engineering applications requiring light weight structural materials.
