摘　　要：铝、镁等轻质合金成为取代钢质材料的理想选材,同时一体化压铸技术的开发及应用有助于实现轻量化。目前可用于车身结构件的铝、镁合金材料有限,且以热处理态的铝合金为主,因此,开发免热处理态的高强韧铝合金具有重要的工程应用价值。大型一体化压铸技术正处于起步阶段,其结构件的设计及其与车身结构的连接、大型压铸装备开发及智能化、模具开发及工艺等方面同样存在重大挑战。此外,镁合金的一体化压铸技术目前处于研究阶段,极具轻量化应用前景。针对近年来一体化压铸铝、镁合金及大型一体化结构部件压铸成形技术进行归纳总结,旨在为一体化压铸大型复杂车身结构件研发提供参考。Al and Mg lightweight alloys are becoming ideal materials instead of steel,while the development and application of integrated die-casting technology also helps to achieve lightweight.Due to the restricted materials available for body structural parts,which is dominated by heat-treated aluminum alloys,the development of heat treatment-free aluminum alloys with high strength and toughness has an important value for engineering applications.Large-scale integrated die-casting technology is in the infancy,and there exists a number of major technical challenges,such as the design of structural parts and connection with the body structure,large-scale die-casting equipment development and intelligent,as well as the development of molds and process.In addition,the integrated die-casting technology of Mg alloy is currently in the research stage,which has great potential for lightweight applications.The die casting forming technology of integrated die-casting Al and Mg alloys as well as large-scale integrated structural components in recent years was mainly reviewed,providing reference for the research and development of integrated die-casting large and complex vehicle body structural components.
