Abstract

Effects of yttrium additions on glass-forming ability of the model system (Cu_0.48Zr_0.48Al_0.04)_100-xY _x (x=0-7 at. %) were studied in detail by using a "perturbation theory" approach. Introduction of the atomic-level strain energy into the driving force for the crystal nucleation well explained the beneficial effects of yttrium additions. It was found that the atomic-level strain energy is related closely to the atomic packing efficiency of the precipitated crystals and less yttrium amount is needed to suppress the precipitation of crystal phase with a higher atomic packing efficiency, which is consistent with the experimental observations.
