Abstract
Available deformation data for superplastic yttria‐stabilized zirconia polycrystals with grain size n for the higher‐purity materials (residual impurity content 0.10 wt%) over the entire stress range. The strain‐rate enhancement with respect to high‐purity materials is related to the grain‐boundary amorphous phase present in such materials.Keywords
