Glass transition temperature of Pd–Cu–Ni–P thin film metallic glass—a 2D approach

This work reports a novel two dimensional approach to the theoretical elucidation of glass transition of the Pd–Cu–Ni–P thin film system, for the first time, with the existing liquid state theories in the realm of transport properties. It is found that this particular combination of metals set a characteristic trend in variation of glass transition temperature irrespective of their compositional ratio. This investigation on these 2D systems uses pentagonal symmetries of variable orientations and justifies their appropriateness in the class of Pd–Cu–Ni–P system. The data obtained are congruent with experimentally measured glass transition temperatures within a maximum of ± 10% variation and underscore the significance of Pd as a glass former.
