Solute partitioning and grain‐boundary chemistry in a commercial Y 2 O 3 ‐bearing partially stabilized zirconia were studied by scanning transmission electron microscopy. The ceramic contained a mixture of twinned monoclinic (minor) phase and cubic (major) phase. Fine‐scale precipitation was noted within the cubic phase. The average measured YiO 3 concentrations in the two phases were near those that would be expected from the binary phase diagram, indicating that solute partitioning approaches completion.
