摘要
概述车身轻量化背景下先进高强钢的研究进展与潜在应用。介绍第三代汽车用中锰钢的化学成分设计与强韧机制,并揭示TRIP(Transformation Induced Plasticity)效应的微观本质。通过分析不同化学成分对中锰钢组织演变和性能的影响,阐明中锰钢高强塑积的形成机制,并讨论中锰钢在汽车工业中的应用前景。
This paper summarizes the research progress and potential application of advanced high-strength steel under the background of lightweight body.In this dissertation,the authors introduced the design of chemical composition and the toughness mechanism of medium manganese steel for the 3 rd generation automobile,and revealed the microscopic essence of the TRIP(Transformation Induced Plasticity)effect.Through analyzing the influence of different chemical compositions on the microstructure and properties of medium-manganese steel,the formation mechanism of high-strength plastic product of mediummanganese steel was clarified,and the application prospect of manganese steel in automotive industry was also discussed.
