Abstract:
An algorithm for modeling the evolution of a monodispersed ensemble of precipitates of a variable composition during heat treatment has been developed. In this algorithm, we for the first time have simultaneously taken into consideration the effect of diffusion processes in particles on their evolution kinetics, as well as the multicomponent nature of the alloy, and diffusion interaction between the components. The proposed method is based on the simultaneous solution of a set of diffusion equations and the balance and thermodynamic equations. A qualitative comparison of the results of calculations of the variation of the carbonitride-precipitate composition over the depth of precipitates upon heat treatment with available experimental data has been performed. © Pleiades Publishing, Inc., 2006.
