摘要：

Computational experiments are used to show that grain boundary (GB) mobility is independent of driving force for a two-dimensional, square-lattice Ising model with Metropolis kinetics. This is established over the entire Monte Carlo (MC) temperature range. A calibration methodology is also provided which endows the MC algorithm with time and length scales and expresses the MC parameters in terms of experimentally measurable quantities. These links are used to verify that the square-lattice MC paradigm delivers the desired sharp-interface grain boundary kinetics over a wide range of mixed driving forces and MC temperatures using a single mobility function.
