On the Kinetics of Grain Growth Inhibited by Vacancy Generation

In recent papers [1,2] we investigated the inhibiting effect of vacancy generation on grain growth. It was shown that vacancies produced as a result of the reduction of the grain boundary (GB) area, i.e. of the elimination of the excess volume, increase the free energy of the system. Therefore, the ‘injection ’ of vacancies into the bulk of the material acts as an inhibiting factor leading to a decrease in the grai
