Grain Boundary Curvatures Measurements in Annealed Yttria‐Stabilized Zirconia (3Y‐TZP) and Their Relation to Mean Grain Size

Abstract

It was determined that the mean grain boundary radius of curvature bold-italicr¯b in 3 mol% yttria‐stabilized zirconia isothermally annealed without and with a DC electric field bold-italicE0∗ = 18 V/cm was uniquely proportional to the mean linear intercept grain size truedfalse¯, the proportionality constant α = 3/2 being in accord with the Rios‐Fonseca stereological model.
