The difference in the shape of creep curves of the gamma single phase single crystal has been investigated, by using the Ni-20mass%Cr single crystals with various crystal orientations. The single crystals are divided into two groups based on the orientation; the crystals with the three kinds of pole orientations in the standard stereographic triangle and the crystals with the orientations with inside the standard triangle. This study is focussed on the creep in crystals with three pole orientations, and their creep curves were investigated as a function of stress. Firstly, the change in creep with decreasing the stress was investigated in detail by using the [001] single crystal, after that the creep of the [001] crystal was compared with those of the [011] and the [111] crystals. The comparisons of the shape of creep curves among the three orientations were done by using the creep rate-time curves and the creep rate-strain curves. In the [001] crystal, the creep curves at lower stresses are different from those at higher stresses. At the stresses less than the critical value, the transient creep stage is drastically extended. In the creep of the [011] single crystal, such an extended transient stage appears even at higher stresses, while the expansion of transient stage does not occur. In the crystal of [111], the transient stage is extended with decreasing stress, while the decreasing ratio of creep rate during the transient stage is smaller.
