摘要：
The objective of this paper is to critically analyse the effect of the gamma' morphology evolution on the creep strain rate behaviour in the temperature range 900 - 1100 degrees C where rafts form in superalloys for single crystal turbine blade and vane applications. A close examination of the experimental results has shown different regimes of strain accumulation depending on the value of the applied stress and temperature. The experimental results have been rationalised in terms of the gamma' shape evolution during creep.
