摘要	Two atomic clusters, Cu8Zr5 and Cu6Zr5 derived from the Cu8Zr3 and Cu10Zr7 phase structures, correspond to two deep eutectic compositions Of Cu61.8Zr38.2 and Cu56Zr44. Cu64Zr36 is the best glass-forming composition in the Cu-Zr binary system. Three e/a-variant composition lines (Cu64Zr36)(100-x)Nb-x, (Cu61.8Zr38.2)(100-x)Nb-x and (Cu56Zr44)(100-x)Nb-x were constructed in the Cu-Zr-Nb system by linking these three specific compositions with the third constitute Nb. The pure Zr and Nb elements were first melted into interalloys, then the interalloys were melted with Cu, and finally alloy bars with diameter of 3 mm were prepared by copper mould suction casting. Minor Nb additions (atomic fraction, x <= 3) can improve remarkably the glass forming abilities of the Cu-Zr alloys. The optimum composition Cu60.3Zr37.2Nb2.5 with the highest T-g/T-1 = 0.626 is located on the e/a -variant line linking the third element Nb and Cu8Zr5 icosahedral cluster and Cu61.8Zr38.2 which possess the deepest eutectic point. The glass formation relative to clusters in Cu-Zr system is also discussed.
