Abstract

Ir- and Rh-base refractory superalloys with an fcc and Ll2 two phase structure similar to Ni-base superalloys, yet with considerably higher melting temperatures have been proposed. Fcc and Ll2 two phases were observed in these alloys by transmission electron microscopy and X-ray powder diffractometry. The compression tests of these alloys showed that the strengths of several alloys were about 200 MPa at 1800°C and these alloys have potential to become ultra-high temperature materials for use in power engineering field.
