Abstract

A new class of alloys based on platinum group metals, which are called refractory superalloys, is proposed. These refractory superalloys have a f.c.c. and L12 coherent two-phase structure (similar to that of nickel-based superalloys), high melting temperatures, and good potential as structural materials for use at temperatures up to 1800°C. In this paper, we report our results on the strength behaviour, creep property, ductility and fracture mode of iridium-based refractory superalloys.
