Abstract:

先进高强度钢已经在汽车上得到了广泛应用，并在汽车的节能、安全、环保等方面表现出了广阔的前景。其与普通高强钢的区别在于它们的显微组织不同，普通高强钢是单相铁素体组织，而先进高强钢基本上是多相组织，主要强化方式为相变强化，其不仅具有高的强度，而且具有良好的成形性能、抗凹性能、能量吸收率高。本文简述了先进高强度复相钢的最新开发和研究进展情况，为复相钢的研究开发提供参考。
Advanced high strength steels (AHSS) are widely used in body-in-white to improve safety, energy saving and reduce emission. Compared with common high strength steel, there are multi-phase microstructures for advanced high strength steels, but the common high strength steel is just a phase ferrite. It is improved strength through achieving hard phase during phase transformation. The advantages of advanced high strength steels are high strength, excellent formability, resisting depressed deformation and energy absorption. This paper describes the latest progress in devel-opment and research of advanced high strength steels to provide some reference for developing complex phase steel.
