Abstract

Rapidly quenched bilayered ribbons comprising one layer as Fe73.5Nb3Cu1Si13.5B9 (FM) and the other layer either as Fe74.5Nb3Si13.5B9 (FNb) or Co72.5Si12.5B15 (CSB) alloy designated as BLFM/FNb and BLFM/CSB, respectively, have been addressed. Phase transformation, thermomagnetic transitions, saturation magnetization, and soft magnetic properties of individual layers were revealed in the functional properties of bilayered ribbons. Properties of bilayer could be endorsed with respect to the single layered Fe73.5Nb3Cu1Si13.5B9, Fe74.5Nb3Si13.5B9, and Co72.5Si12.5B15 alloy ribbons. Selective devitrification of the layers in the bilayers could be induced through optimum heat treatment. Enhanced bend sensitivity was revealed in BLFM/CSB through generation of desirable phases in the bilayers of the bilayered ribbon. Synergistic diffusivity of Fe and Co with its consequent effect on interfacial zone of BLFM/CSB bilayer was observed. (C) 2013 AIP Publishing LLC
