Structural, morphological and Magnetic studies of Soft magnetic Fe-Si-B Metallic Glass ribbons

Abstract A comparative study of two metallic glass ribbons produced by two different industries namely M/s Honeywell corporation, U.S.A., and M/s Vijay electricals. The potential of different experimental techniques like XRD, SEM and EDAX and VSM has been carried out for two soft metallic glass ribbons. XRD studies reveal that for sample A has two broad peaks and sample B shows the absence of any sharp peaks indicating crystalline secondary phases are <5%. Morphological studies show that sample A has homogeneous matrix whereas sample B has crystallites of varied shapes and sizes distributed in the range of 5-40 μm. EDAX for both the samples A and B was done to investigate the compositional elements. VSM measurements reveals sample B to exhibit a relatively larger anisotropy compared to sample A.
