Further information
Subsequent to casting this sample was subject to an annealing treatment which served to recrystallise the sample. Evidence of this can be found in the annealing twins visible in several of the grains. These are a consequence of growth accidents during recrystallisation. Their shape is determined by the need to minimise interfacial energy. There is no strain energy associated with such twins and hence they do not have pointed ends.
