Abstract
Computer simulations of domain coarsening have given excellent agreement with patterns observed experimentally in grain-boundary networks. In contrast, the statistical distribution functions predicted by scaling theories do not agree well with these. We identify the cause of the failure to be a size correlation effect that is a consequence of the topological connectivity of the network. The scaling analysis is accordingly modified and leads to much better agreement with the observations.Keywords
