Martensitic transformations of zirconia precipitates in magnesia‐partially‐stabilized zirconia (Mg‐PSZ) have been observed directly in a transmission electron microscope. By controlling the electron beam to produce heating and cooling cycles, the precipitates could be repeatedly transformed between monoclinic and tetragonal. Preliminary observations of the resultant precipitate microstructures are presented.
