摘要
长期服役于复杂环境中的高强钢承重构件表面会产生剥落腐蚀,在交变载荷作用下,承重构件极易发生脆性破坏,耐久性问题日益突出。基于材料自身、环境因素及载荷作用等方面,总结了近年来高强钢及其焊接接头的研究成果,主要包括材料的腐蚀损伤机理、静力拉伸性能、滞回性能与疲劳性能。最后,对腐蚀环境中高强度钢的发展前景进行了展望。
After long-term service in a complex environment,exfoliation and corrosion happen on the surface of load-bearing components of high strength steel.Under the action of alternating loads,the load-bearing components are prone to brittle failure.So the durability problem becomes increasingly prominent.The research achievements of high strength steel and their welded joints in recent years are summarized,mainly including corrosion damage mechanism,static tensile performance,hysteretic performance and fatigue performance,based on the aspects of material itself,environmental factors and load effects.Finally,the research prospect of high strength steel in corrosive environment is proposed.
