Compression deformation experiments are conducted to investigate the recrystallization behavior during the dynamic recrystallization (DRX) and static recrystallization (SRX) of high-manganese steel in terms of flow stress and microstructure morphology. The experimental results indicate that strain rate plays a key role on DRX style. A low strain rate promotes discontinuous dynamic recrystallization (DDRX), whereas a high strain rate encourages continuous dynamic recrystallization (CDRX). The steady-state stress of DRX behavior decreases with increasing deformation temperature regardless of the true strain and strain rate. Deformation temperature is a vital factor in determining the softening fraction of SRX behavior. The effect of interpass time on austenite grain size is weak for SRX behavior. The SRX kinetics equation for the designed high-manganese steel is proposed according to experimental results.

高锰奥氏体钢的再结晶行为和组织演变

进行压缩变形实验以研究高锰钢在动态再结晶 (DRX) 和静态再结晶 (SRX) 过程中的再结晶行为，包括流动应力和微观组织形态。实验结果表明，应变率对 DRX 样式起着关键作用。低应变率促进不连续动态再结晶 (DDRX)，而高应变率促进连续动态再结晶 (CDRX)。无论真实应变和应变速率如何，DRX 行为的稳态应力都随着变形温度的升高而降低。变形温度是决定 SRX 行为软化分数的重要因素。对于 SRX 行为，道间时间对奥氏体晶粒尺寸的影响较弱。
