Abstract

Excellent soft magnetic properties of Fe82Cu1B 12Si4Nb1 alloy is obtained by concentration variation of metal elements Fe and Nb, and metalloid B and Si elements. But the crystallization temperature of Fe82Cu1B 12Si4Nb1 alloy is shifted to lower range in contrast to Fe73.5Cu1B7Si15.5Nb 3 alloys. The value of activation energy of primary crystallization by Kissinger equation is (236±10.6) kJ and (295±5.3) kJ for Fe82Cu1B12Si4Nb1 and Fe73.5Cu1B7Si15.5Nb3 glass alloys respectively. The relationship between the time of maximum nucleation rate of the primary crystallization with different heating rate t= (Tp1-Ton)/Thr and activation energy Ep1 and Eon is yielded. The grain coarsens easily for Fe82Cu 1B12Si4Nb1 in contrast to Fe 73.5Cu1B7Si15.5Nb3 glass alloy. © 2011 Published by Elsevier Ltd.
