Effect of Isothermal Annealing on Crystallization Mechanism of Amorphous Ni65Cr16P19 Metallic Alloys

Crystallization behavior of amorphous Ni65Cr16P19 metallic alloy during the isothermal annealing process from 617 K to 648 K was studied using differential scanning thermal analysis and X-ray diffraction analysis. Two crystallization peaks are observed. The activation energies E A for the crystallization are determined to be 403 kJ/mol and 306 kJ/mol for the first and the second peak, respectively. Ni crystals precipitate in the first peak by a two-dimensional crystallization mechanism with a constant nucleation rate, and stable Ni3P crystallizes in the second peak. With the use of the Avrami index, the activation energy for nucleation of the Ni crystal is determined to be 470 kJ/mol.
