Residual stresses in a SiC-TiB_2 particulate composite before and after stressing have been measured using X-ray diffraction. Tensile residual stresses in the TiB_2 drop by 60% after bending stresses of 250 MPa are applied. Likewise, the compressive residual stresses in the SiC phase decrease accordingly. Such behavior is consistent with stress-induced microcracking.
