A mathematical model has been developed to predict the stress-strain Curves of a Ti-IF steel during hot deformation. This model is based on a phenomenological representation of the shape of the stress-strain curves and the traditional theories for constitutive equations which incorporate the power law. This equation expressed in terms of peak stress, peak strain, steady state stress and one additional parameter. The stress-strain curves of Ti-IF steel obtained by this model are in good agreement with experimental results. (c) 2005 Elsevier B.V. All rights reserved.
