    Vacuum brazing of alumina to alumina and Fe-Ni-Co or Ti has been studied experimentally using commercial active filler materials. A specimen design in accordance with the requirements of testing both shear strength and NDT by the C-SAM method is developed. The specimen geometry as well as the true bonded area has a great effect on the measured strength values, which vary from 24 to 237 MPa. A good correlation between the results from NDT and strength testing is found. This data is important for the R&D work on components constructed of joined metal and ceramic parts because no general standards are available today for the testing of dissimilar joints.
