摘要：

A model of creep deformation in arbitrarily oriented nickel-base superalloy single crystals has been developed. This model extends the preceding model of the present authors [Svoboda, J. and LukaS, P., Acta mater., 1998, 46, 3421] covering the case of creep in [001] oriented crystals. The calculated creep curves were compared with the creep curves of single crystals CMSX-4 of the orientations [001], [011] and [111] measured at 750 degrees C; a fair agreement was found.
