Accuracy of High-Temperature, Constant Rate of Strain Flow Curves


The components that make up a mathematical model of hot strip rolling include the conditions of equilibrium, roll deformation, friction at the roll-strip interface, and material behavior. The consistency and accuracy of the predictive capability of the model will depend on the quality and rigor of the representations of these components. This paper deals with one of the least tractable parameters—material behavior.

The difficulties associated with the determination of constitutive behavior are discussed. It is suggested that a standard method of testing for high-temperature strength be established.
