【 摘 要 】

In this article we propose a mesoscopic model of the interphase interaction in binary metal alloys. The difference of partial molar volumes of the components of alloy was taken into account during the mathematical model building. The simulated sample is represented as a two-dimensional region, divided into square cells of nanometric size that are characterized by the value of concentration and belonging to the phase. Intermediate phase of alloy can include arbitrary forms. The proposed mesoscopic model provides a phase cells change and the implementation of the law of conservation of matter. Software implementation of the developed model is executed. The results of computer simulation are compared with the results of laboratory experiments interphase interaction in a binary metal alloy Mg-Al. The obtained computer model allows a numerical study of the evolution of the phase composition of alloy in the process of diffusion interaction.
