摘要:
通过铝合金的应用实现汽车轻量化是节能减排的有效手段之一,国内汽车公司长期依靠进口铝合金汽车板,从成本、效率方面影响了汽车轻量化的进程,铝合金汽车板的国产化及应用技术的研究开发对推动我国汽车、特别是新能源汽车的轻量化至关重要。总结了5XXX、6XXX和7XXX系铝合金汽车板材及应用技术的研究成果,重点围绕中铝材料应用研究院开展的合金成分-工艺-金属组织基本性能及应用性能的关联性研究进行系统总结,包括:覆盖件外板用6XXX系铝合金板材的包边性能与晶粒组织、漆刷线与织构、烤漆强化效果与团簇的关联性;覆盖件内板用5XXX系铝合金板材的屈服强度与晶粒尺寸的Hall-Petch关系、吕德斯带与金属组织的关系;结构件用热成形铝合金板材及相关热成形技术;铝合金汽车板成形极限的预测与冲压成形模拟仿真技术;自冲铆连接过程模拟仿真技术;磷化、锆薄膜化、硅烷化表面处理技术。希望为铝合金汽车板的国产化及进一步提升铝合金汽车板的性能提供参考。
Abstract:
Vehicle lightweighting utilizing aluminum alloys is one of the effective means to achieve energy saving and emission reduction. For a long time, automotive companies at home rely on imported aluminum alloy automotive sheets, which affects the process of vehicle lightweighting due to high cost and low efficiency. The research and development of domestication and application technology of aluminum alloy for automotive body sheets is very important to promote the vehicle lightweighting, especially new energy vehicles. This review summarizes the research results of 5XXX, 6XXX, 7XXX series of aluminum alloy automotive body sheets and the related application technology, carried out in Chinalco Material Application Research Institute. The research focuses on the correlation among chemical composition, process, microstructure, basic properties and application properties: the correlations between the hemming performance and grain structure, between roping and texture, between baking strength and clusters in 6XXX outer panel sheet;the Hall-Petch relationship between yield strength and grain size, relationship between Lüdes band and microstructure in 5XXX inner panel sheet; aluminum alloy sheets and related hot forming technologies for hot stamped structural parts. For application technology, this review summarizes the prediction of the forming limit diagram and stamping simulation technology for aluminum alloy automotive body sheets, simulation technology for self-piercing riveting, surface treatment technologies including cleaning, passivation and phosphating, zirconium thin film, salinization. We wish that this review lay the foundation for the domestication and further performance improving of aluminum alloy automotive body sheets.
