Numerical Modeling of Residual Stresses and Fracture Strengths of BaSrCoFeO in Reactive Air Brazed Joints.

Reactive Air Brazing (RAB) enables the joining of vacuum-sensitive oxide ceramics, such as BaSrCoFeO (BSCF), to metals in a one-step process. However, damage may form in ceramic or joint during RAB. In this work, experimental microstructure characterization, measurement, and prediction of local material properties using finite element analysis were combined to enlighten these damage mechanisms, which are currently not well understood.
