The mechanical and microstructural characteristics of multiaxially forged (MAF) Mg were investigated in the present work. Three conditions of the alloy such as cast, solutionised at 773K for 2 hours and solutionised at 773 K + ageing at 473 K for 10 hours were used for multiaxial forging. The reduction of 50 percent in each pass was imparted to the sample leading to a true strain of 2.1 (one cycle) and 4.2 (two cycles) at a temperature of 723 K. SEM/EBSD and TEM characterization of the MAF samples were made to substantiate the grains refinement and deformation behaviour of the alloy. The processed Mg alloy exhibits better tensile strength and ductility as compared to the as cast and heat treated alloy. The ductility and strength of the alloy after multiaxial forging have significantly enhanced. EBSD and TEM analysis revealed the formation of recrystallised grains due to dynamic recrystallisation during forging.
