Abstract

Creep data, at 973 K and stresses between 355 and 512 MPa, in flat specimens of PE-10 nickel-base superalloy are reported. The data have been interpreted in terms of a constitutive equation based on a creep model involving dislocation climb and cross-slip over the strengthening phase. Strain-rate sensitivity and apparent activation energy have also been measured and analysed in the frame of the proposed model.
