Abstract

The X-ray diffraction method was used to measure the triaxial state of residual stresses in each phase in the following four kinds of composites; ZrO2/Al2O3 composite, WC-Co alloy, SiC/Al-alloy composite, and TiC/SiC coating. The residual macrostress and microstress were determined from the phase stresses by using the rule of mixture. The effects of heat treatment and surface finishing on the residual stress were studied. The measured value of the thermal residual stress was compared with the theoretical prediction based on the mismatch of the coefficient of thermal expansion.
