Abstract

The crystallization kinetics of the Ni45Ti23 Zr15Si5Pd12 alloy has been investigated by DSC and XRD. The process of crystallization is multi-stage proceeding. The isothermal activation energy obtained from Arrhenius equation increases with the process of crystallization. Based on the JMA equation, the average Avrami exponent for the main crystallization process is larger than 3.0, indicating the crystallization to be a three-dimensional nucleation and growth. The large atomic size difference and negative heats of mixing increase the thermal stability of the Ni-based amorphous alloy.
