Abstract
A reliable and accurate prediction of flow behavior of metals considering the coupled effects of strain, strain rate and temperature is crucial in understanding the workability of the metal and optimizing process parameters for hot forming process.In this study, two phenomenological based constitutive models namely; modified Fields-Backofen (m-FB) and Khan-Huang-Liang (KHL) have been developed for flow stress prediction of Austenitic Stainless Steel (ASS) 316. Uniaxial tensile tests have been performed in the temperature ranges of 150°C– 600°C and strain rate ranges of 0.0001– 0.01s-1 for analyzing the deformation behavior. The prediction capability of these models have been verified with experimental data using various statistical measures such as correlation coefficient (R), average absolute error (Δ) and its standard deviation (S). Based on the analysis of statistical measures revealed Khan-Huang-Liang (KHL) model has good agreement with experimental flow stress data.
