Irradiation induced amorphization in metallic multilayers and calculation of glass-forming ability from atomistic potential in the binary metal systems

This review attempts to present first a brief summary of the up-to-date experimental studies on amorphization transition, which results in the formation of amorphous alloys or metallic glasses, by ion irradiation of multiple metal layers in the binary metal systems. Secondly, based on the framework of Miedema’s theory, thermodynamic modeling of metallic glass formation is described with consideration of the significant role of interfacial free energy of the multilayers in amorphization. Thirdly, results of molecular dynamics simulations for some representative systems are presented to show the calculation of the intrinsic glass-forming ability from interatomic potential of the binary metal systems.
