Creep behavior of Ni-added Ir85Nb15 two-phase refractory superalloys at 1800 °C

Abstract

To provide information relevant to Ir-based two-phase alloys for future ultra-high-temperature applications, the compression creep properties for the Ni-added Ir85Nb15 alloys were investigated at 1800 °C under 137 MPa. The results show that Ni addition has a significant effect on the creep resistance of the Ir85Nb15 two-phase refractory superalloy.
