... Abstract The misorientation of a boundary of a growing grain is defined not only by its crystallography but also by the crystallography of the grain into which it is growing. This article focuses on the Monte Carlo Potts model that is typically used to model grain growth, Zener-Smith pinning...

... grain growth was developed by Zener, as communicated by Smith ( Ref 46 ). Movement of the grain boundary requires pulling away from the pinning effects of the particles. However, as the grain boundary no longer exists on the area occupied by the particles, it must be recreated as the boundary pulls away...

... is an effective grain refiner because the NbC precipitates pin the austenite grain boundaries during hot rolling and during solutionizing heat treatment ( Ref 12 , 64 , 65 ). The smaller average ferrite grain diameter due to the presence of NbC precipitates in these steels contributes to the total strengthening...

Finally, the reversed-capillary technique ( Fig. 21b ) allows one to obtain relatively large driving forces, although unfortunately only in the beginning of the experiment...
