Grain size analysis

Using grain boundary maps, a grain size analysis can be carried out (see manual). The results of StripStar (for software, see appendix) are histograms of volume densities of 3-D grain size (radii of spheres).
Grain size analysis of experimentally deformed Black Hills quartzite (see 4.2) shows that the recrystallized grain size is constant, i.e., the volume of recrystallized grains increases as recrystallization progresses but not the grain size itself. In contrast, both the volume fraction and the grain size of the old grains decrease with increasing recrystallization (Heilbronner & Tullis, 1999a)
