摘要
During the superplastic deformation of alumina-zirconia ceramics, the way how the intercalation mechanism between grains of the two phases occurred has been put forward. It corresponds to the formation of a protuberance on a grain of one of the phases, located at a triple junction, which grew by penetrating in the boundary separating two grain of the other phase. When these grains are completely separated, a change in the grain surroundings has occurred that has been studied. It has been observed that the intercalations favoured the growth of alumina clusters.
