Creep deformation modelling of superalloy single crystals Original Research Article

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 Lukáš, 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°C; a fair agreement was found.
