Effects of Re content and crystallographic orientation on creep behavior of aluminized Ni-base single crystal superalloys

► Aluminide coating diminish the creep strength of superalloys. ► Re content improved the creep properties of superalloys. ► Crystallographic orientation influenced the creep strength of superalloys. ► Deformation mechanism in aluminized superalloys on (1 0 0) and (1 1 0) side-surfaces was discussed.
