摘要
综述了近来年高锰孪晶诱发塑性/相变诱发塑性(TWIP/TRIP)钢的研究进展和实际应用情况。介绍了晶粒尺寸对TWIP钢变形机制的影响,观察了形变孪晶随晶粒尺寸变化的演变过程。总结了形变诱导马氏体和形变诱导孪晶的演变机理。简述了碳化钒(VC)沉淀粒子对高锰TWIP/TRIP钢延迟断裂及加工硬化行为的影响,并对VC沉淀粒子与形变孪晶的交互作用机制进行了探讨。阐述了双辊铸轧工艺制备高锰TWIP/TRIP钢薄带的近终成型工艺过程及显微组织的演变机理,并探讨了工程应用的前景。
The present progress and applications in research on high manganese twinning induced plasticity and transformation induced plasticity（TWIP/TRIP）steel were summarized. The influence of grain size on TWIP effect was investigated. The evolution of grain size was investigated,which the mechanism of deformation twin evolution was analyzed. The deformation mechanism of deformation induced martensite and deformation twin was investigated. The effect of vanadium carbid（VC）precipitates on the delayed crack and strain hardening behavior was investigated , and the interaction between VC precipitates and deformation twin was discussed. The post-treatment technology,microstructure,mechanical properties and deformation mechanism of high manganese TWIP/TRIP steel fabricated by using twin-roll strip casting were investigated.
