Vacuum brazing Mo using Ti-Ni-Nb braze alloys

► A novel approach of brazing Mo using three clad Ti-Ni-Nb foils has been performed in the experiment. ► Similar microstructural evolution of the joint is observed for three brazing foils. ► The joint using 60Ti-25Ni-15Nb foil brazed at 1250 °C for 600 s demonstrates the highest bending strength of 526 MPa. ► The clad Ti-Ni-Nb foils show potential in brazing Mo for industrial application.
