Hot Deformation Behavior and Strain Rate Sensitivity of 33MnCrB5 Boron Steel Using Material Constitutive Equations

Abstract In this paper, the constitutive equation parameters (Johnson–Cook parameters) of 33MnCrB5 material were determined with help tensile tests. Initially, Johnson–Cook (JC) model was used for performing simulations sample finite element analysis ANSYS software. For these operations, first at a certain temperature (24 °C) and low strain rates (10 −1 , 10 −2 −3 s ) quasi-static tests performed. Then, high performed rate values temperatures 300 °C, 600 900 respectively. Finally, JC belonging to test materials found in accordance results obtained from last stage, simulation software yield stress, maximum elongation compared experimental results. As result, deviation are calculated as 5.04% 5.57% 5.68% elongation, while temperature, stress is 9.42%, 11.49% value 7.63%. The accuracy verified comparison made data.
