Abstract
Partially stabilized zirconia materials are well known for their combination of high strength and toughness. In this study a new ytterbia samaria co-stabilized zirconia is manufactured by intensive co-milling of zirconia and stabilizer oxides with subsequent consolidation by hot-pressing. Evolution of microstructure, mechanical properties and phase composition are studied with respect to sintering temperature. The material exhibits a transformation dominated fracture behavior and a combination of high strength of up to 1050 MPa, a fracture toughness exceeding 12 MPa√m and an excellent resistance to low temperature degradation.
