In order to evaluate the strength of Si3N4/SUS304 joints with Cu interlayers, bending tests were carried out from room temperature to high temperature in air, vacuum, or argon gas. Fractography and fracture mechanics studies were also carried out. The results obtained are as follows, The typical crack initiation site is the interface between Si3N4 and a brazing filler. The crack propagates along the interface, and kinks into Si3N4. The bending strength is not influenced by the testing atmosphere (air, vacuum, argon). When testing temperature is under 300°C, bending strength is constant, and when testing temperature over is 300°C, bending strength decreases because of the softening of the brazing filler. When αmin is over 30μm, the stress intensity factor considering residual stress, Κpr, at which the crack kinks into Si3N4 is constant and almost agree with the fracture toughness, Κic, of monolithic Si3N4. On the other hand, when αmin is under 30μm, Κpr is lower than the fracture toughness of monolithic Si3N4.
