On the stability of grain structure with initial Weibull grain size distribution

A microstructure with a Weilbull grain size distribution (GSD) was generated and subjected to normal grain growth (NGG) by the Monte Carlo Potts method. The results show that the GSD keeps almost invariant during NGG. The Weibull function fits well the steady-state GSDs evolving from the Weibull and the Hillert distributions.
