Correlation between mechanical properties such as internal friction and shear modulus and the microstructure of ALON-based composite ceramics incorporated with BN was investigated at elevated temperatures in air. Internal friction (Q-1) of the ALON-based composite ceramics exhibited peaks, independent of the amount of BN added, at around 250-350°C, 700-750°C and 1000-1100°C, then increased monotonically at 1250°C which is the maximum temperature measured, On the other hand, by high temperature X-ray diffractometry (XRD), ALON (Al(64+x)/3_??_(8-x)/3O32-xNx) and BN phase, and aluminum borates oxidized both, were identified as the microstructures (formed crystalline phases) formation temperatures of the phases corresponded to the three peaks of internal friction (Q-1). However, shear modulus measured at the same time with internal friction, decreased monotonically with temperature and did not reflect any microstructural change at high temperature. Therefore, it was clarified that the microstructural evolution of ALON-based composite ceramics at high temperature, can be detected by internal friction measurement.
