AbstractCyclic tensile fatigue tests were performed on 100 +/- 20 nm, and 0.35 mu m 3Y-TZP ceramic specimens at room temperature. Localized superplastic deformation of the grains in the 100 nm materia I at and near to the fracture surfaces was fi rst identified by AFM imaging. Slip band-like microfeatures, similar to those reported on some metals, were also unexpectedly seen to develop on the side faces. In contrast, the 0.35 mu m specimens retained their equiaxed grain morphology after undergoing similar testing conditions. The micromechanisms underlining these phenomena were discussed. Grain boundary diffusion of the respective atomic species is reasoned to be the major governing process in operation. And the contribution of a dislocation slip mechanism is considered to play a possible or parallel role. (C) 1998 Chapman & Hall.
