Magnesium-rare earth based alloys are increasingly being investigated due to the formation of highly stable strengthening phases, activation of additional deformation modes and improvement in mechanical properties. Several investigations have been done to study the effect of rare earths when they are alloyed to pure magnesium and other Mg alloys. In this review, the mechanical properties of the previously investigated different magnesium-rare earth based binary alloys, ternary alloys and other higher alloys with more than three alloying elements are presented.

A magnesium alloy was fabricated through the consolidation of chips accumulated during the turning process, followed by cold compaction and hot extrusion. A variation in the depths of cut was done during turning to understand the effect of deformation imparted during primary processing on the mechanical properties of an AZ91 alloy (Mg–9 wt.% Al–1 wt.% Zn–0.3 wt.% Mn). The results revealed a significant improvement in compressive strengths (up to 75%) with increased depth of cut, without compromising ductility through the development of fine-grained structures and prior plastic strain induction. This approach resulted in superior materials vis-a-vis conventional deformation techniques and promotes cost and energy efficiency through recycling industrial metal swarf, which is a significant environmental and economic concern.
