Abstract
ⶠMechanical strength and interface property of Ir-base superalloys are calculated. ⶠThe Ir3Hf bulk seems less brittle than f c c Ir, while Ir3Nb becomes more brittle. ⶠThe chemical bonding in Ir3Nb is stronger and more directional than that in Ir3Hf. ⶠDescending sequence of mechanical properties of Ir and Ir3X is: Ir â Ir3Nb â Ir3Hf â Ir3Zr. ⶠThe (1 0 0)-I interfaces are energetically favorable with high bond strengths.
