| To investigate the microstructural evolution and mechanical properties of 20CrMoA steel shafts during warm cross wedge rolling (CWR), this study systematically examined the effects of rolling temperature, cross-sectional area reduction, and die geometric parameters. The evaluation was conducted utilizing optical microscopy, electron backscatter diffraction (EBSD), and uniaxial tensile testing. The results reveal that 800 °C is the critical boundary temperature for achieving refined and uniform equiaxed grains. Increasing the area reduction to 50% significantly enhances deformation penetration, thereby promoting dynamic recrystallization (DRX) in the core region. Under these optimized processing conditions, the synergistic effect of the dual-phase microstructure comprising martensite and ferrite substantially elevates the tensile strength of the rolled workpiece to 1268.8 MPa. Furthermore, the CWR deformation induces the formation of a strong α-fiber texture and a relatively weak γ-fiber texture. Elevating the temperature to 800 °C or optimizing the die parameters (decreasing the forming angle and increasing the stretching angle) can effectively weaken the {001}<110> texture and promote the evolution of grain orientation toward the {111}<112> component. These micro-texture tailing effects contribute to an optimized crystallographic orientation and enhanced microstructural uniformity across the workpiece. This study provides a vital theoretical basis for microstructural control and process parameter optimization in the warm CWR of high-performance shaft components. |
