Abstract

Xmol%CeO2-ZrO2 (x=14-34) pseudo-single crystals grown by floating zone method were uniaxially compressed in the range of 0 to 1400 MPa at 700°C to examine the effect of axial ratio (c/a) on the critical stress of ferroelastic domain switching. The critical stress markedly increased with axial ratio. It could be understood, considering the Landau theory and the ferroelastic domain switching model based on the tetragonal to cubic second order ferroelastic transition, that the critical stress was proportional to the cube of (c/a-1).
