摘要

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. In this paper, an attempt is made to systematically present and elegantly discuss the conjoint influence of yttrium, cerium and zinc oxide additions to pure magnesium. The developed nanocomposite revealed a combination of superior microstructure and mechanical properties (microhardness, strength and ductility). The microscopic mechanisms governing both strength and ductility of the engineered nanocomposite were examined through carefully conducted study of microstructure 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 microscopic mechanisms governing mechanical behavior.
