| 超高强度钢因其卓越的力学性能在航空航天、汽车制造等高端制造领域应用广泛。当前,超高强度钢的研究主要聚焦于强度与韧性协同提升,通过合金化设计与优化、纳米析出相调控、表面处理技术及轧制工艺优化等多种强韧手段来实现材料性能突破。本文全面综述了超高强度钢发展历程,重点阐述低合金超高强度钢、二次硬化钢、马氏体时效钢及其他先进高强钢的强韧化机理,分析了合金元素、纳米析出相、TRIP 效应和轧制工艺对其组织性能的影响。未来,超高强度钢的发展将着眼于热处理工艺优化、激光增材制造技术应用、材料基因组计划以及生产线的改进与完善,以期开发出兼具低成本、超高强度和优异韧性的新型材料。 |
| 英文摘要: |
| Ultra-High Strength Steel (UHSS) is widely utilized in high-end manufacturing sectors such as aerospace and automotive engineering due to its outstanding mechanical properties . Current research on UHSS primarily focuses on the synergistic enhancement of strength and toughness, achieved through various strengthening and toughening strategies including alloy design and optimization, control of nano-precipitates, surface treatment technologies, and advanced rolling processes . This article provides a comprehensive review of the development history of UHSS, with emphasis on the strengthening and toughening mechanisms of low-alloy UHSS, secondary hardening steels, maraging steels, and other advanced high-strength steels. It also analyzes the influences of alloying elements, nano-precipitates, the TRIP effect, and rolling processes on microstructures and properties . Future development of UHSS will aim at optimizing heat treatment processes, applying laser additive manufacturing technologies, leveraging the Materials Genome Initiative, and improving production lines, with the goal of developing new materials that combine cost-effectiveness, ultra-high strength, and excellent toughness . |
