The design of two-phase Ir or Rh-based alloys with compositions (Ir, Rh) 75-Nb15Ni10, which had reduced densities and retained their desirable properties, was discussed. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to analyze the microstructure of alloys. Results showed that the alloys has the higher specific strength compared with Ir, Rh, and Ta-based alloys and is comparable to W-based alloys at 1600 °C.
