Abstract

High strength (1270 MPa) and tough (>9 MPa m(1/2)) zirconia-toughened alumina (ZTA) ceramics with a helical spring shape were produced from sol-derived pastes comprising a mixture of boehmite (gamma-AlOOH) and nano-size zirconia powders using extrusion. It is shown that the mechanical response of the extruded ZTA ceramics can be controlled/altered by manipulating the microstructure. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd.
