摘要：

The constitutive equations for the flow behavior of a commercial 0.34 pct C-1.5 pet Mn-0.7 pet Si-0.083 pet V-0.018 pet Ti microalloyed steel were determined. For this purpose, uniaxial hot compression tests were carried out over a wide range of strain rates (10(-4) to 10 s(-1)) and temperatures (1123 to 1423 K). In combination with models developed in the literature, the experimental results permit the flow stress of the present steel to be predicted within +/-5 pet. It is shown that the classical constitutive equations must be modified to take the grain size into account, particularly when the latter is below 30 mu m.
