Abstract The formation of rafts by the ordered [gamma]-phase under a tensile load at high temperatures is one of the most interesting features of nickel-base superalloys. It has been investigated by many authors, both theoretically and experimentally. From elasto-plastic finite-element calculations of it is known that matrix channels depending on their orientation to the load axis experience quite different stress levels. In order to determine the influence of these different stress levels on phase chemistry and phase growth, in this work the phase compositions of the single crystal superalloy SRR99 have been analyzed after creep experiments at T = 980 C and T = 760 C in [001] direction.
