摘要
基于汽车轻量化的大背景,铝合金因其优异的综合性能成为汽车用板材的优选材料。主要综述了汽车车身板用变形铝合金的研究进展,以汽车车身板材常用的2×××、5×××、6×××和7×××系变形铝合金的应用现状为基础,结合国内外研究者现阶段的研究成果,对各系变形铝合金应用在汽车车身板中的优劣势展开了分析。在此基础上,着重介绍了各系合金的主要强化方式、常用成分及使用状态,并概述了汽车车身板用材料的主要使用性能。最后,总结了各系变形铝合金在汽车车身板中的使用性能特点,并对变形铝合金在汽车车身板中的应用前景及主要研发方向做出了展望。
Based on the background of automobile lightweight, aluminum alloy has become the preferred material for automobile sheets because of its excellent comprehensive properties. In this work, the research progress of wrought aluminum alloys for automobile body sheets was reviewed. The application status of 2×××, 5×××, 6××× and 7××× series wrought aluminum alloys for automobile body sheets was reviewed. Based on the research results of domestic and foreign researchers, the advantages and disadvantages of various strains of wrought aluminum alloy used in automobile body sheet were analyzed. On this basis, the main strengthening methods, common components and application status of each series of alloys were emphatically introduced, and the application properties of automotive body sheet materials were summarized. Finally, the performances of all kinds of wrought aluminum alloys in automobile body sheets were summarized, and the application prospect and main research and development direction of wrought aluminum alloys in automobile body sheets were prospected.
