摘要：

Acoustic emission (AE) and acousto-ultrasonics (AU) have been employed to monitor the thermally induced damage which occurs when alumina and zirconia-toughened alumina ceramics are quenched from elevated temperatures into aqueous solutions. The AE and AU parameters were correlated with the microcracking and the strength degradation associated with the thermal shock treatments.
