N2 - In the present study, we report the formation of the Mg-based bulk metallic glass (BMG) samples by spark plasma sintering of the amorphous powders prepared by ball-milling. The sintering was performed in the supercooled liquid region (Tg - Tx) and fully glassy Mg-based samples were successfully sintered at 398 K. The deformation on the surface associated with Vickers indentation hardness tests of the compacts reveals the presence of the semi-circular shear-bands around the indents and also reveals inhomogeneous nature of plastic deformation.
