Abstract

The large bulk glassy [(Fe0.5Co0.5) 0.75B0.20Si0.05]96Nb4 alloy specimens with the diameters up to 7.7 mm have been prepared by water quenching the melt immersed in the molten flux of B2O3 The maximum diameter of the obtained specimens is approximately 1.5 times as large as the previous result for copper mold casting should be cooled at the higher rate than that of water quenching, The flux melting improves the glass-forming ability by the elimination of oxides and other inclusion in the molten metal which act as heterogeneous nucleation sites for crystallization.
