| Abstract: | Residual stresses in a SiC-TiB2 particulate composite before and after stressing have been measured using X-ray diffraction. Tensile residual stresses in the TiB2 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. |
