Abstract

For the present study, [(Fe_0.5Co_0.5) _0.75B_0.20Si_0.05]₉₆Nb₄ bulk metallic glasses (BMGs) were cast as cylinders with 2 mm diameter and 50 mm length. The first crystallized product, the metastable Fe₂₃B ₆-type like phase, forms as a result of primary crystallization. The thermal stability and the crystallization kinetics were studied using the isochronal and isothermal DSC curves, measured at different heating rate and temperatures. Despite their good glass-forming ability (GFA) and high stability against crystallizations, their incubation time prior crystallization is almost zero. In order to rule-out the complete crystallization mechanism, in situ time resolved studies using the synchrotron radiation were done. The magnetic properties of the BMGs are strongly related to their structure and will be presented as well.
