This study investigates thermal mismatch stresses in the lamellar microstructure of the solid solution directionally solidified eutectic (DSE) oxide Co1-xNixO/ZrO2(CaO). X-ray and neutron diffraction measurements were performed on isolated eutectic domains to measure the residual strain and stress tensors. Maximum principal residual stresses on the order of 1 GPa were recorded, with the Co1-xNixO and the ZrO2(CaO) phases maintaining states of tensile and compressive stress, respectively. The stress tensors for these materials are compared with measurements for similar DSE oxide systems and suggest that solid solution DSEs might be used to tailor the residual stress states in DSE composites.
