WebJan 1, 2001 · Grain boundary statistics, based on misorientation, can be extracted from such maps. The statistic usually quoted is the length (i.e. projected area) of certain grain boundary types, such as low angle boundaries, twins or other CSLs, which can be measured and outputted as a proportion of the total grain boundary length. crystal downs whitehall mi
