A generalised constitutive description of deformation of engineering alloys that exhibit a dominant tertiary creep is presented that extends a previous treatment of creep deformation. The model parameters of the constitutive equations that are determined by analysis of creep curves are supplemented by the Young's modulus to provide a database from which illustrative calculations are made. Simulations of constant strain rate, stress relaxation and high strain low cycle fatigue (both strain and stress control) are made for the superalloy IN738LC; the predictions are compared with limited available experimental data.
