摘要
在汽车工业发展需求的节能环保与高安全性的双重目标下,Fe-Mn-Al-C低密度钢因其低密度和优异的力学性能,具有巨大的应用潜力,引起了国内外的广泛关注。因此,综述了Fe-Mn-Al-C低密度钢的合金成分与微观组织、生产工艺、强化机制及其性能的研究进展;对目前Fe-Mn-Al-C低密度钢中提出的变形机制及其拉伸性能、冲击韧性和疲劳性能进行阐述分析;最后总结了Fe-Mn-Al-C低密度钢研究现状中存在的不足,并提出了其未来研究方向。
Fe-Mn-Al-C low-density steels have attracted considerable interest as low density and excellent combination of strength and ductility with the requirements of fuel consumption, environment sustainability and passenger safety. The current status of alloy design and microstructures, processing, strengthening mechanism, properties in Fe-Mn-Al-C low-density steels are reviewed. In this review, the development of deformation mechanisms of Fe-Mn-Al-C low-density steels, as well as tensile property, impact toughness and fatigue property are introduced and discussed. The existing problems and future challenges in Fe-Mn-Al-C low-density steels are pointed out to established as structural materials for automotive industries.
