Abstract :
In order to examine the melt temperature effects of alloys with varying degrees of glass forming ability, the magnetic properties of nanocrystalline Fe73.5Cu1Nb3(Six B1-x)22.5 (x=0.4-0.8) alloys are investigated. It is found that for all the alloys, except for x=0.8, the soft magnetic properties of the ribbons quenched at the high melt temperature are better than those of the ribbon fabricated at the low melt temperature, and that the magnitude of improvement in the magnetic properties with increased melt temperature decreases with decreasing glass-forming ability. It is argued that the glass-forming ability of an alloy should be taken into account in considering the melt temperature effects
