本文的目的是介绍用于汽车工业的先进高强度钢（AHSS）的基本概念，包括化学成分设计、热加工过程中的微观结构和机械性能发展、生产技术表征、潜在应用和服役性能。AHSS钢被认为是该生产部门未来应用的主要材料。与冷成形的单相深拔钢不同，AHSS钢的力学性能受多种因素控制，包括：相组成和在整体组织中的分布、相组分的体积分数、尺寸和形貌以及亚稳组分的稳定性。这些钢的主要特点是它们不允许依赖于公认的传统的微观结构-性能关系。因此，不同的钢铁生产商仍在开发许多不同的合金概念和替代加工路线，以生产可比较的钢等级。
The aim of this paper is to present the basic concepts of advanced high strength steels (AHSS) for use in the automobile industry, including chemical composition design, microstructure and mechanical properties development during thermomechanical processing, production technology characterisation, potential applications and performance in service. AHSS steels are considered to be the major materials for future applications in this production sector. As opposed to the cold formable single phase deep-drawable grades, the mechanical properties of AHSS steels are controlled by many factors, including: phase composition and distribution in the overall microstructure, volume fraction, size and morphology of phase constituents, as well as stability of metastable constituents. The main feature of these steels is that they do not permit to rely on the well-established traditional microstructure-properties relationships. Therefore, many different alloy concepts and alternative processing routes are still under development by different steel producers for comparable steel grades.
