GRAIN-BOUNDARY MISORIENTATION DISTRIBUTIONS IN MONOCLINIC ZIRCONIA

Possible grain boundary structures and distributions in monoclinic zir conia are Crystallogeometrical analysis was employed to evaluate some special, low-energy boundaries in the material. A computer simulation was then used to model the grain boundary misorientation and character distributions based on certain assumptions about crystallographic tex ture and orientation correlations which influence the formation of low -energy grain boundaries. The possible relevance of the results obtain ed to optimization of the protective properties of zirconia films is d iscussed.
