It was proposed that a new class of alloys based on platinum group metals (PGMs) were called refractory superalloys. These refractory superalloys have an fcc and L12 coherent two-phase structure (similar to that of Ni-based superalloys), high melting temperatures and good potential as structural materials used at temperatures up to 1800°C. Our recent results on the microstructure evolution, deformation and fracture behavior of some of these refractory superalloys, especial Ir-and Rh-base refractory superalloys were reported.
