Abstract

The effect of temperature on grinding-induced texture in tetragonal lead titanate (PT) has been investigated as a function of the magnitude of loading applied to the sample surface during grinding, using in situ x-ray diffraction (XRD) with an area detector. 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 °C and undergoes smaller changes in lattice parameter or tetragonality versus temperature during in situ thermal cycling between room temperature and approximately 100 °C above the T C. Inhibited depoling of ground PT materials investigated by in situ texture measurements demonstrates the effects of residual stresses.
