Modeling of Concentration and Temperature Dependencies of Incubation Time at Decomposition of Solid Solution by Monte Carlo Method

Abstract

Uu; 82.56.Lz MODELING OF CONCENTRATION AND TEMPERATURE DEPENDENCIES OF INCUBATION TIME AT DECOMPOSITION OF SOLID SOLUTION BY MONTE CARLO METHOD * The article presents the application of Monte Carlo method to the kinetics of nucleation at the decomposition of a binary solid solution with a face-centered cubic lattice. We built a phase diagram of a binary solid solution by Monte Carlo method and found the dependence of incubation time on supersaturation of solid solution at different reduced temperatures in metastable regions. Obtained results of the computer experiment are compared with the classical nucleation theory, in which the nucleus is born at once with almost optimal composition, and then just grows.

“…Therefore, one should, first of all, simulate the equilibria in solid solutions and construct the Monte Carlo (MC) phase diagram. It was done in [53].…”
