Residual stress induced failure of Ti-6Al-4V/Si3N4 joints brazed with Ag-Cu-Ti filler: The effects of brazing zone’s elasto-plasticity and ceramics' intrinsic properties

•Brazing of Ti-6Al-6V and polycrystalline Si3N4 ceramics having different intrinsic properties.•Comparative mechanical and microstructural characterizations of the brazed metal/ceramics joints.•Quantitative analysis of the local elasto-plastic properties of as-received filler and brazing zone by nano-indentation.•Validation of experimental bending strengths by thermo-mechanical finite-element-analysis based on nano-indentation results.
