In this paper, we report the formation of a series Zr-(Cu,Ag)-Al bulk metallic glasses (BMGs) with diameters at least 20 mm and demonstrate the formation of about 25 g amorphous metallic ingots in a wide Zr-(Cu,Ag)-Al composition range using a conventional arc-melting machine. The origin of high gla
The cluster line approach is presented and applied for searching the optimum glass-forming composition in the Cu-Zr-Al system. Three cluster selection rules are proposed: topologically dense packing (atomic size-related), chemical short-range order as evaluated by dissimilar atomic pairs, and compos
The structural relaxation in a Zr 55 Cu 30 Ni 5 Al 10 bulk metallic glass was investigated by volume and enthalpy relaxation at various temperatures. The relaxation kinetics was well described by a stretched exponential relaxation function, UðtÞ ¼ exp½Àðt=sÞ b . The Kohlrausch index, b, ranged from
