Abstract
In this investigation an algorithm is given to simulate the flow stress curves for multipass hot deformation processes simply from the data obtained from singlepass hot torsion test Using the obtained multipass curves the value of norecrystallization temperature T nr is calculated This method is examined on a Nbmicroalloyed steel Maximum error in calculation of T nr with this method and the values obtained from empirical tests was 15 which is a very low value The predicted results are found to be in accord with the experimental data
