Abstract

The aim of this work was to describe the deformation resistance of austenitized Ti-IF steel in the temperature range of 650 to 1100°C by a complex equation. The mean flow stress was determined by an original procedure, based on laboratory rolling of flat samples. Deformation resistance was described by a single formula, using a cumulative function in which particular terms are multiplied by a coefficient of 1 or 0, in dependence on a specific temperature. Calculation of specific coefficients had to be proposed in such a way that they could react to exceeding temperature boundaries between individual phase regions. The developed model can be used for off-line predictions of power/force parameters in the forming of Ti-IF steel, in a wide range of conditions of hot and warm deformation.
