To eliminate the effect of processing parameters, a methodology involving the introduction of various amounts of the m-phase into one specimen disc is explored. With this method, the formation of the m phase can be attributed to the reduction of Ce4+ to Ce3+ in Ce–TZP. Oxygen vacancies play a key role in the aging behavior. Although the addition of Al2O3 particles refines the Ce–TZP microstructure, their presence reduces the aging resistance of Ce–TZP.journal article10.1016/j.oceram.2024.1005642-s2.0-85186869513https://api.elsevier.com/content/abstract/scopus_id/85186869513
