The potential of active brazing filler metal modification by ceramic particle addition, with the aim of reducing the stresses in ceramic‐metal joints is studied. A layered braze structure is proposed: layers of reinforced and un‐reinforced filler are combined in an optimal manner to minimize residual stress. The joints are tested in 4‐point bend tests. The evaluation of residual stresses and the optimization of the braze layout are carried out by FE modelling.
