T. Kiguchi et al., EFFECT OF AXIAL-RATIO ON CRITICAL STRESS OF FERROELASTIC DOMAIN SWITCHING IN CERIA-PARTIALLY-STABILIZED ZIRCONIA, Nippon Seramikkusu Kyokai gakujutsu ronbunshi, 105(10), 1997, pp. 871-875
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 a
t 700 degrees C to examine the effect of axial ratio (cia) on the crit
ical stress of ferroelastic domain switching. The critical stress mark
edly increased with axial ratio. It could be understood, considering t
he 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).
