Abstract

The effect of phase separation on ferroelastic domain switching in 3 mol%Y₂O₃-ZrO₂ pseudo-single crystals annealed at 1700°C was examined. Domain switching occurred in two steps. From TEM analysis, the first step seemed to be the switching of t′-phase, and the second to be that of t-phase. The effect of phase separation is as follows. First by, the switching amount of t′-phase decreased with decrease of the volume fraction, whereas that of t-phase increased with increase of the one. Secondly, the critical stress of t′- and t-phase increased with growth of t-phase colony. This is because that the clamping force among these phases for domain switching increase. Especially the critical stress of t-phase was strongly effected by the colony size of t-phase.
