研究了一种渗铝镍基单晶高温合金的中高温蠕变性能。结果表明，（1 0 0）侧面试样的持久寿命比（1 0 0）侧面试样的持久寿命长。这意味着发生了垂直于主取向的次取向的各向异性。渗铝试样的各向异性蠕变行为是由两个侧面试样之间的{1 1 1}滑移系的不同排列引起<1 0 1>的。
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.
