Kurzbeschreibung (Abstract)

Fine-grained (Mg, Y)-PSZs containing small amounts of spinel as a second phase have been produced by pressureless sintering and hot isostatic pressing. Their mechanical proper ties have been optimised by judicious adjustment of processing parameters such as sintering temperature, cooling Pare and holding time of eutectoid heat treatments. Hot isostatic pressing reduces the internal defect size in comparison with conventional sintering. Without exploiting transformation toughening, high strength values of more than 700 MPa are obtained which rise to about 900 MPa after eutectoid ageing. Failure mechanisms are discussed in terms of defect size, defect type and R-curve behaviour. (C) 1997 Elsevier Science Limited.
