A B S T R A C T In this study toughness of alumina toughened zirconia (ATZ) was improved by co-stabilization by shifting from co-precipitated yttria stabilized zirconia powder to yttria neodymia co-stabilized starting powders in which the stabilizers were introduced by intensive milling. Alumina contents were varied between 0.5 and 20 vol.-%. Test samples were consolidated by hot pressing. Microstructure, phase composition, mechanical properties and LTD were studied. The results show thatdoi:10.1016/j.oceram.2021.100119 fatcat:eva3go4pgbc7tndrtfs52llsq4
