The authors have presented a Monte-Carlo simulation of grain growth and solute segregation on the grain boundaries (GBs) in binary alloys. A thermodynamic approach of the simulation algorithm has been given. The preliminary simulation of a simplified binary system indicates that pronounced solute segregation on the GBs is achieved, characterized by linearly increasing solute concentration on the GBs and significant spatial correlation of the solute distribution. The authors observe the normal grain growth in the present system by demonstrating the scaling behavior of its size distribution although the kinetics is seriously slowed down, exhibiting an exponent much lower than the 1/2 law.
