The effects of various Nb, Ni, Mo, B, and C content on the microstructures and deformation behaviours of Ir-Nb fcc-L12 two-phase refractory superalloys were investigated at both room and high temperatures. The results showed that the intergranular fracture occurring in Ir single-phase alloys could be governed by controlling the microstructures around GBs and alloying Ni, B and C in Ir-15at%Nb two-phase alloys. The results also showed that Ir-15at%Nb two-phase refractory superalloys alloyed with about 10at% Ni were superior to the binary Ir-15at%Nb two-phase alloy as an ultra-high temperature structural material in terms of strength, fracture behavior, and density.
