MICROSTRUCTURE AND MECHANICAL PROPERTIES OF Mg – Sn ALLOYS SYNTHESIZED BY DISINTEGRATED MELT DEPOSITION TECHNIQUE
Abstract
Magnesium (Mg) and its alloys are suitable for aerospace and automotive applications, due to their low density and high specific strength. Mg – Al – Zn alloys and Mg – Al – Mn alloys are the widely used commercial alloys as they possess nominal strength and ductility at ambient temperature (27 oC). However, owing to the presence of the Mg17Al12 phase that is thermally unstable at temperatures > 120 oC, these alloys have relatively poor microstructural stability and low strength-retention characteristics at elevated temperatures. For high temperature applications, such as in power-train components of automobiles, magnesium alloys are expected to exhibit both microstructural stability and mechanical stability (i.e. retention of strength) at elevated temperatures. Although alloys such as those containing zirconium, and those incorporated with rare earth metals are being used/developed for enhanced thermal stability, these elements are expensive and hence are suitable only for critical applications.
