In order to research the flow behavior of 20CrMnTi and obtain its constitutive equation, the isothermal compression tests of 20CrMnTi were carried out using the Gleeble—3500 thermo-simulation machine, up to a 60% height reduction of the sample at strain rate range from 0.01 s⁻¹ to 10 s–1 and deformation temperature range from 1123 K to 1273 K.

... At present, the methods for constitutive model construction were divided into three categories: the phenomenological type, the physical type and the machine learning type [3]. The Arrhenius model was one of the most widely used phenomenological constitutive models Furthermore, some researchers have proposed a variety of correction methods for the original Arrhenius model due to its poor prediction accuracy, such as strain compensation [4][5][6][7], multi-condition of deformation to find material parameters [8][9][10], optimal algorithm to optimize material parameters [11], etc. The Zerilli-Armstrong model was a fundamental physical constitutive model based on the theory of thermally activated dislocation motion. ...
