Flakes with a size of 20×4×0.8mm3 and rods of (Fe68B25Nd7)96Nb4 bulk metallic glass (BMG) with a diameter of 1.5 and 3mm were cast. Rods a diameter of 1.5 mm were proven to be XRD amorphous. High vacuum environment during the fabrication will benefit the formation of fully amorphous BMG. The super-cooled liquid regions of (Fe68B25Nd7)96Nb4 is 59℃ and the reduced glass transition temperature is 0.624 indicating good glass-forming ability. The critical cooling rate for glass formation for (Fe68B25Nd7)96Nb4 melt is about 294℃/s by computer simulation (Fe68B25Nd7)96Nb4 BMG shows soft magnetic property while partially crystallized sample shows hard magnetic property.
