Structural changes of 2.5‐mol%‐Y 2 O 3 ‐stabilized tetragonal ZrO 2 polycrystal fractured surfaces, as well as ground, polished, and annealed surfaces, were studied by X‐ray diffraction. Much greater intensity of the (200) tetragonal peak than (002) was found on the thin surface layer of the ground specimen, but not on the fracture surface. The intensity changes were discussed in relation to the toughening mechanism.
