Abstract
Creep behaviour of various alumina, zirconia and zirconia-toughened al umina is investigated. A very large scale of creep rates and creep beh aviours is observed. Creep rate depends on the grain sie, on the purif y and on the composition of the glassy phase present in grain boundari es. Cavitation and microcracking by grain boundary sliding have been i dentified as the main creep mechanisms. (C) 1997 Elsevier Science Limi ted.
