A diffusionless cubic (c)..-->..metastable tetragonal (t') phase transformation occurs in certain alloys in the ZrO/sub 2-/Y/sub 2/O/sub 3/ system on quenching from elevated temperatures. Microstructural features due to this phase transformation, principally anti-phase domain boundaries (APB's) and mechanical accommodation twins, have been characterized using transmission electron microscopy. Certain differences between the authors' interpretation and those of other workers are discussed.
