Abstract
- Abstract: Excellent soft magnetic properties of Fe82Cu1B12Si4Nb1 alloy is obtained by concentration variation of metal elements Fe and Nb, and metalloid B and Si elements. But the crystallization temperature of Fe82Cu1B12Si4Nb1 alloy is shifted to lower range in contrast to Fe73.5Cu1B7Si15.5Nb3 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 Fe82Cu1B12Si4Nb1 in contrast to Fe73.5Cu1B7Si15.5Nb3 glass alloy. [Copyright &y& Elsevier]
