Abstract
Ce‐TZP is reported to exhibit cyclic transformation during machine grinding. Previous conclusions were based on the results obtained by grinding Ce‐TZP at a single speed and depth of cut. In the present work, grinding parameters were carefully chosen to induce varied stresses. Results show that Ce‐TZP exhibits cyclic transformation, not always, but only under certain favorable grinding conditions. Results are supported by XRD, optical microscopy, and dynamometric observations. Three stages of transformation, namely, a mechanical‐stress‐induced t to m, a frictional‐heat‐driven m to t, and a thermal‐quenching‐stress‐induced t to m, in sequence, are clearly identified.
