Title: On the crystallization kinetics and micro-structural transformations of Fe40Ni38B18Mo4 alloys
Author: Hysen, Thomas; Senoy, Thomas; Ramanujan, R V; Anantharaman,M R
Abstract: Activation energy for crystallization (Ec) is a pertinent parameter that decides the application potential of many metallic glasses and is proportional to the crystallization temperature. Higher crystallization temperatures are desirable for soft magnetic applications, while lower values for data storage purposes. In this investigation, from the heating rate dependence of peak crystallization temperature Tp, the Ec values have been evaluated by three different methods for metglas 2826 MB (Fe40Ni38B18Mo4) accurately. The Ec values are correlated with the morphological changes, and the structural evolution associated with annealing temperatures is discussed.
