Summary

The residual stress distribution in microwave sintered metal-ceramic functionally graded materials consisting of Ni/8YZrO2(ZrSiO4) was analysed. In order to get information of the residual stress state in the bulk of the material in dependence of the composition, high energy X-rays delivered from an electron storage ring allowing high spatial resolution was chosen. The stress state was found to be related to the compositional distribution of the present phases and the coefficients of thermal expansion. The partial substitution of 8Y-ZrO2 by ZrSiO4 in the ceramic rich area of the sample influences the residual stresses on micro- and macroscopical scale.
