Abstract
Optical microscopy and acoustic emission have been used to study the phase transition in PbTiO3 crystals. It is established that the acoustic-emission activity depends on the angle between the normal to the interphase boundary and the direction of a uniform temperature gradient. It is shown that the orientation of the interphase boundary is determined by the post-growth defect system of the crystals.
