摘要:
交通工具轻量化是应对能源和环境危机的重要举措,采用轻质高强的铝合金制作交通工具是实现轻量化的有效途径。目前,低强度5000(Al-Mg)和6000(Al-Mg-Si)系变形铝合金已成功用于汽车车身。高强7000(Al-Zn-Mg-Cu)系铝合金可作为替代汽车钢结构件的潜在材料使用,但其受成形性方面的限制而无法在汽车领域获得广泛应用。7000系铝合金的成形性已引起人们极大的研究兴趣,系统研究高强7000系铝合金的成形工艺并使之用于制备汽车结构件对交通工具轻量化具有重要意义。近年来,国内外学者针对7000系铝合金的成形性开展了一系列尝试和研究,并获得了一定成果。基于此,总结了7000系铝合金的冷成形、温成形及热成形(尤其是成形-淬火一体化技术)方面的研究进展,重点介绍了成形工艺对其成形性及最终成形件显微组织、力学性能的影响,分析了不同成形工艺的优缺点及应用前景。最后,展望了7000系铝合金成形技术的未来发展趋势。
Abstract:
Lightweighting of vehicles is an important response to the energy and environmental crises, and building vehicles by adopting aluminum alloys with high specific strength is an effective way to meet this objective. At present, low-strength 5000(Al-Mg)and 6000(Al-Mg-Si)series aluminum alloys have been successfully applied to automotive bodies. High-strength 7000 (Al-Zn-Mg-Cu) series aluminum alloys, as an ideal candidate to replace steel structural parts, cannot be widely used in automobile industry due to their poor formability. The formability of 7000 series aluminum alloy has attracted more and more attention. Thus, for vehicle lightweighting, it is of great significance to systematically study the forming technologies suitable for 7000 series aluminum alloy and promote their application in vehicle structural parts. Recently, researchers have carried out a series of attempts and studies on the formability of 7000 series aiuminum alloys and have yielded some positive results. This article presents an overview of the research progress on cold forming, warm forming and hot forming (especially hot form quench technique) of 7000 series aluminum alloys. The influence of forming processes on the formability of alloys, as well as microstructures and mechanical properties of final parts, was introduced in detail. The advantages/disadvantages and future application of different forming processes were also analyzed. Lastly, the development of forming technologies for 7000 series aluminum alloys was forecasted.
