to fully realize the benefits it must be usable in more applications including those that require
higher strength and ductility. It has been known that fine grain size in Mg alloys leads to high
strength and ductility. However, the challenge is how to achieve this optimal microstructure
in a cost effective way. This work has shown that by using optimized high shear deformation
and second phase particles of Mg 2 Si and Mg x ZnZr y the energy absorption of the …
