Crystals of yttria partially stabilized zirconia were grown by the arc‐image floating‐zone technique and studied by transmission electron microscopy. Crystals annealed at 1700°C consist of tetragonal precipitates and a cubic matrix. The platelike domains in a precipitate are twin‐related tetragonal variants stacked alternately parallel to the (011) twin plane. The axial relations between the tetragonal precipitate and the cubic matrix are [100] tetragonal |[100] cubic , [011] tetragonal |[011] cubic .
