摘　　要：先进高强度钢(AHSS)以其出色的力学性能在汽车、航空航天及海洋工程等领域展示了巨大的潜力,伴随着它们的广泛使用,其在海洋环境中的腐蚀行为成为限制其发展应用的因素。近年来研究者对AHSS的力学性能和腐蚀行为进行了深入分析,在AHSS的微观组织演变、力学性能提升和腐蚀行为调控策略等方面展开了系统的实验和理论研究,发现TRIP效应对力学性能及腐蚀行为都有影响。本文归纳整理了典型的第三代AHSS的特点及发展概况;综述了AHSS在海洋环境中的力学性能以及腐蚀行为的研究进展;总结出TRIP效应一般可以提高AHSS的力学性能,但同时可能会引发局部应力集中和应力腐蚀开裂,降低钢材的耐腐蚀性能。文末提出了腐蚀防护措施,并对未来的研究方向进行了展望。Advanced high-strength steel has demonstrated tremendous potential in fields such as automotive,aerospace,and marine engineering due to its excellent mechanical properties.However,with the widespread use of advanced high-strength steel,its corrosion behavior in marine environments has become a factor restraining its development and application.Consequently,in recent years,researchers have conducted in-depth analyses of the mechanical properties and corrosion behavior of advanced high-strength steel.They have carried out systematic experimental and theoretical studies on microstructural evolution,mechanical property enhancement,and corrosion behavior control strategies.It has been found that the transformation-induced plasticity(TRIP)effect has a significant impact on both the mechanical properties and corrosion behavior.This paper summarizes the characteristics and development overview of typical third-generation advanced high-strength steel,reviews the research progress on the mechanical properties and corrosion behavior of advanced high-strength steel in marine environments.It concludes that the TRIP effect generally improves the mechanical properties of advanced high-strength steel but may simultaneously induce local stress concentration and stress corrosion cracking,thereby reducing the corrosion resistance of steel.It ends with a proposal of the corrosion protection measures,and a discussion on the future trends.
