A crystallographic theory has been proposed that takes into account an
elastic matching of the polydomain (twinned) phases and allows to pre
dict an evolution and interchange of three phases in perovskite-type f
erroelectric single crystals. A diagram connecting these phases with t
he possible domain structures and their reconstruction has been discus
sed.
