Abstract
The crystallization mechanism from amorphous matrix during the annealing in Cu-Pd and Cu-Pt alloy systems has been examined by using Molecular Dynamics (MD) simulation with an Embedded Atom Method (EAM). The effects of the addition of Cu on the crystallization have been discussed in terms of radial distribution function, Honeycutt-Andersen (HA) cluster analysis index. Moreover, the crystallization evolution at different annealing temperatures has been obtained using Avrami exponents based on volume-fraction. On the other hand, the crystallization process for different Cu concentrations have been investigated by cluster-type index (CTIM) methods enabled to sort the structure of different-type polyhedrons. Our simulation results show that the forming of crystal phase related to the presence of crystal-type polyhedrons and Cu concentration. The crystal phase forming ability increases with Cu content at different annealing temperatures.
