A magnesium alloy-based nanocomposite [Mg-1.8Y-0.4Ce-1.53ZnO] was developed using the technique of disintegrated melt deposition (DMD) followed by hot extrusion. The developed nanocomposite revealed a combination of superior mechanical properties, to include microhardness, strength and ductility. It has been established that the three additions of yttrium, cerium, and zinc oxide (ZnO) contribute to altering the properties of both pure magnesium and a magnesium alloy metal matrix. In this study, an attempt has been made to systematically evaluate the conjoint influence of the three additions to pure magnesium on response kinetics of the engineered nanocomposite. The microscopic mechanisms governing both strength and ductility of the engineered nanocomposite were examined through carefully conducted study of microstructural development using an optical microscope, scanning electron microscope, and x-ray diffraction (XRD) texture analysis. Microstructure-mechanical property correlation studies were performed with the prime objective of understanding and rationalizing the governing microscopic mechanisms.
