摘要：

Metal/ceramic bonds subject to residual stress caused by thermal expansion misfit have been investigated in an Al2O3/Ta(Ti) system. The residual stresses cause cracking of either the Al2O3 or the interface, dependent on the magnitude and sign of the residual stress. The observed locations, orientations, and trajectories of the cracks have been rationalized on the basis of residual stress fields, energy release rates and fracture energies for the ceramic and the interface.
