The creep behavior of Ni-based single crystal superalloys small degree deviated from [001] orientation is strongly influenced by temperature, γ? phase size and the level of applied stress. This article presents a review on effects of small orientation deviation on creep behavior of single crystal superalloys. Different creep properties of the alloys with orientation deviation originate from different creep deformation mechanisms. Besides, these mechanisms correspond to different threshold stress which are associated with the occurrence of primary creep and creep rate. At intermediate temperatures, the creep behavior of single crystal alloys is highly sensitive to small misorientation but relatively insensitive above 850 °C. The size of γ? phase is inferred to exert influence on the creep behavior of alloys with orientation deviation at intermediate temperatures. However, at elevated temperatures, the rafting process can be accelerated by higher thermal activation, thus the mechanical properties become less relevant with the size of γ? precipitates coarsening.
