Dissimilar infrared brazing of CoCrFeMnNi equiatomic high entropy alloy (HEA) and 316 stainless steel using BNi-2 and MBF601 fillers has been investigated. The wettability of both fillers at 50 °C above their liquidus temperatures on both substrates is great. The BNi-2 brazed joints are dominated by Ni-rich matrix with borides in the center of brazed zone and tiny borides at the interface between the braze and substrate. The MBF601 brazed joints are comprised of phosphide and Fe/Ni-based matrix. The joint brazed with the BNi-2 filler at 1020 °C for 300s has the highest shear strength of 392 MPa and the cracks with cleavage dominated-fracture are propagated through the borides in the Ni-rich matrix. Both fillers show the potential in dissimilar brazing the CoCrFeMnNi HEA and 316 stainless steel.
