Detail of 19. Original grains contain subgrains that grade into recrystallized grains toward their margins or in linear zones that may have been fractures or local shear zones. The similarity between low-angle subgrains and high-angle recrystallized grains in shape and size suggests that progressive rotation is the dominant process of dynamic recrystallization; dislocation creep regime 2.
