Notes:
XAFS measurements of the Cu, Ni and Zr K-edges for the melt-quenched Zr67Cu33 and Zr67Ni33metallic glasses were curried out using synchrotron radiation at 20K. Fitting calculations for theEXAFS results reveal that local structure around Ni and Zr in Zr67Ni33 is well represented by thosefor the crystalline Zr2Ni, while local structure around Zr in Zr67Cu33 is better fitted by anicosahedron rather than crystalline Zr2Cu. Such differences of the local structure attribute to thedifferences of the stability of super-cooled liquid state and glass formability between Zr67Cu33 andZr67Ni33 metallic glasses
