Microstructure and Mechanical Characteristics of AZ31B/Al2O3 Nanocomposite with Addition of Ca

ABSTRACT: The present study addresses the development of a AZ31B–Al2O3 nanocomposite. AZ31B–Al2O3 nannocomposite is known to exhibit excellent ductility matching with that of pure aluminum but with limited strength levels. Addition of Ca is shown in this study to lead to a simultaneous improvement in 0.2%YS, UTS and hardness while the ductility was compromised. The ductility, however, stayed 30 % higher than the ductility of monolithic AZ31B. The results suggest that this alloy-composite has significant potential in diverse engineering applications when compared to AZ31B or AZ31B–Al2O3 nanocomposites.
