Abstract
Hot torsion tests were conducted to simulate forging processes in two vanadium microalloyed steels, types 40MVS6 and 30MSiV62, varying both the conditions of test temperature and time as well as the strain and strain-rate conditions, in order to obtain final results comparable to the classic Q+T steels, direct from the forge. The Zener-Hollomon equations were also calculated, indicating the conditions of application which theoretically permit the prediction of forging parameters, in accordance with the needs or possibilities of an industrial plant.
