Abstract: | The crystallization kinetics of a melt spun Fe-Ni based alloy has been investigated, with both isothermal and continuous heating
experiments, by means of differential scanning calorimetry. The alloy presents two separated crystallization processes. In
order to perform the kinetic analysis of a melt spun metallic glass and to decide which kinetic model agrees better with the
experimental crystallization data as the crystallized fraction x. We compare the experimental dependence of ln(k0f(x)) vs. (1-x) and that predicted, assuming different model equations for f(x). Both crystallization processes follow the JMAE equation and the master curve is the same for isothermal and non-isothermal
data.
