Compared to the ground PT under lower loading conditions (5 N), the ground PT under higher loading conditions (40 N) retains strong ferroelastic texture near the Curie temperature (T-C) around 350 degrees C and undergoes smaller changes in lattice parameter or tetragonality versus temperature during in situ thermal cycling between room temperature and approximately 100 degrees C above the T-C. Inhibited depoling of ground PT materials investigated by in situ texture measurements demonstrates the effects of residual stresses.
