Advanced metal alloys laboratory aims to develop metallic alloys for both basic and applied science purposes. Research in this laboratory mainly focuses on synthesis of metallic alloys, amorphous metallic alloys, glassy steels and metallic glass/nanocomposites for possible applications such as coating materials, magnetic materials and bulk materials. Current research projects include investigation of structural hierarchy and multiscale morphological selection during devitrification of metallic alloys including metallic glasses and metallic glass nanocomposites and their characterizations under far from equilibrium conditions and phase transformations in Mn-Al magnets. The laboratory is equipped with an arc melting furnace which allows us to produce metallic alloy rods in various sizes and shapes.
