Two zirconia-toughened aluminas, one with a small addition of titanium dioxide, have been studied to determine their mechanical behavior between room temperature and 1,300{degree}C. Room-temperature fracture toughness and bend strength were also determined in samples aged at 1,00{degree}C for 720 h. Results show that the titania addition enhances the inelastic behavior of the composite at 1,300{degree}C. Segregation of Ti on alumina grain boundaries was also measured.
