Abstract

Abstract

To characterize the high-temperature flow behavior of Fe-27Mn-10Al-1.0C lightweight steel, high-temperature compression tests were performed using a Gleeble-3800 thermal simulation testing system under experimental conditions of 850-1050 ℃ and 0.01-10 s⁻¹. Based on the Fields-Backofen (FB) model, a constitutive modeling study was conducted using the experimental data. By introducing a temperature softening term and accounting for the strain effects as well as the coupling effects of strain, strain rate, and temperature on model parameters, a modified M-FB model was successfully established. The prediction accuracy of the M-FB model was validated using statistical parameters, including the correlation coefficient (R), average absolute relative error (AARE), and relative error (RE). The research results indicate that Fe-27Mn-10Al-1.0C lightweight steel is significantly sensitive to strain, strain rate, and deformation temperature. The predicted data of the M-FB model are highly consistent with the experimental data, and it can be reliably applied to predict its high-temperature flow behavior.
