Mechanics of large strain extrusion machining and application to deformation processing of magnesium alloys

► Confinement and controllability of deformation field, including effecting SPD. ► Enhancing workability of alloys through combinations of large hydrostatic pressure and in situ deformation-induced heat. ► Deformation processing of Mg alloys into sheet/foil forms in a single step without preheating. ► Creation of fine grained and UFG Mg alloys. ► Scalability of LSEM for commercial production of sheet forms.
