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. |
