Steady-state grain-size distributions resulting from grain growth in two dimensions

Using a previously described technique for simulation of grain growth, the steady-state grain-size distributions resulting from grain growth in two dimensions are described. In particular, it is demonstrated that the grain size distribution in the scaling state is best fit by a Weibull distribution function instead of the commonly-cited lognormal or Rayleigh distribution functions. Further, it is shown that the constant rate of change of the average grain size is equal to the grain boundary mobility constant.
