Using Micro-Alloying (0.5Zr-0.4Ce) to Significantly Enhance Hardness, Tensile and Compressive Response of Magnesium

Abstract:

A ternary micro Mg-0.5Zr-0.4Ce alloy is developed using disintegrated melt deposition method (DMD) followed by hot extrusion. The developed alloy exhibited superior mechanical properties i.e. microhardness, strength and ductility under tensile and compressive loading. In particular, the alloy exhibits excellent ductility (>25%) under both tensile and compressive loading. The mechanisms leading to strengthening and ductilization were examined through microstructural studies involving optical microscope, SEM and XRD texture analysis. Microstructure-property correlation studies are performed to understand these mechanisms.
