Determination of flow stress and the critical strain for the onset of dynamic recrystallization using a sine function
Abstract
A new model has been developed to estimate the flow stress under hot deformation conditions up to the peak of the stress-strain curves. The model is constructed on the basis of the general form of sine functions by introducing an additional exponent. Besides, an equation is derived from the model, which could be used to predict the critical strain for the onset of dynamic recrystallization. The model has been examined for a 304 austenitic stainless steel. The estimated flow stress had an average percentage error of %1.66. 9 pages, 6 figures, 1 appendix Written in spring of 2012, as an independent work
