Abstract
A diffusionless cubic (c)→metastable tetragonal (t′) phase transformation occurs in certain alloys in the ZrO2‐Y2O3 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 our interpretation and those of other workers are discussed.Keywords
