Abstract

An aluminized Ni-based single-crystal superalloy was examined to investigate the anisotropic creep properties at intermediate and high temperatures. It was found that the specimens with a (1 0 0) side surface showed longer creep rupture life than the specimens with a (1 0 0) side surface. This means that anisotropy of the secondary orientation, which is normal to the primary orientation, occurred. The anisotropic creep behavior of the aluminized specimen was induced by a different arrangement of {1 1 1}〈1 0 1〉 slip systems between the two side-surface specimens.
