Abstract
Isothermal crystallization kinetics of Ni24Zr76 amorphous alloy has been studied by differential scanning calorimetry (DSC). Theoretically estimated transient times are found to be consistent with the experimentally observed incubation periods. The crystallization kinetics has been analyzed in terms of Kolmogorov-Johnson-Mehl-Avrami (KJMA) model and significant departure from the linear KJMA behavior was observed. Such non-linearity is due to the surface-induced crystallization, anisotropic growth of the crystals, impingement effects and variation of the nucleation rate during crystallization etc. By applying high-resolution electron microscopy (HREM), it has been shown that the nucleation and growth of the crystals do not take place at a constant state of disorder.
