“…The Mössbauer study of the as-received sample and the specimens annealed at 400°C and 500°C, on analysis, provide the precipitating phases (α-(Fe-Co)) and ((Fe-Co) 3 β). Similar phase precipitations have been reported (Bhatnagar et al 1985) in earlier crystallization studies of the present system.…”

The Fe-based multicomponent amorphous alloys (also referred to as metallic glasses) are known to exhibit soft magnetic properties and, it makes them important for many technological applications. However, metallic glasses are in a thermodynamically metastable state and in case of high temperature operating conditions, the thermally activated crystallization would be detrimental to their magnetic properties. The study of crystallization kinetics of metallic glasses gives useful insight about its thermal stability. In the present work, crystallization study of Fe 67 Co 18 B 14 Si 1 (2605CO) metallic glass has been carried out using differential scanning calorimetry (DSC) technique. Mössbauer study has also been undertaken to know the phases formed during the crystallization process. The alloy shows two-stage crystallization. The activation energy has been derived using the Kissinger method. It is found to be equal to 220 kJ/mol and 349 kJ/mol for the first and second crystallization peaks, respectively. The Mössbauer study indicates the formation of α-(Fe, Co) and (Fe, Co) 3 B phases in the alloy.
