|Issue Date:||2010||Citation:||Nguyen, Q.B., Gupta, M. (2010). Improving compressive strength and oxidation resistance of AZ31B magnesium alloy by addition of nano-Al2O3 particulates and Ca. International Journal of High Performance Computing Applications 24 (1) : 883-896.

Microstructural characterization studies revealed equiaxed grain structure, minimal porosity, and good matrix-reinforcement interfacial integrity. The results also showed that addition of both nano-Al2O3 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. © The Author(s), 2010.||Source Title:||International Journal of High Performance Computing Applications||URI:||http://scholarbank.nus.edu.sg/handle/10635/85297||ISSN:||10943420||DOI:||10.1177/0021998309349551|
