- 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.
