Abstract
Traditional magnesium alloy manufacturing has often relied on processing within a temperature range that results in liquid phase formation of some of the constituents. These methods are often limited by the equilibrium phase formation states available from the melt. In this work, we will present findings on a recently developed processing approach that enables complex, unique microstructural evolution (often to persistent metastable states) while remaining in the solid phase state. Specifically, the shear assisted processing and extrusion (ShAPE ) method as applied to Mg alloys will be presented. Novel microstructural pathways, textural formation and mechanical properties will be discussed. These results point to the ability to design and engineering novel Mg materials with unprecedented properties and performance.
