摘要：

航空航天与汽车领域高性能、轻量化的发展趋势下，铝合金应用越来越广泛，材料强度越来越高、构件形状越来越复杂，对先进的成形制造技术提出了更高的挑战。热冲压技术利用材料高温状态下良好的塑性，可一次整体成形出薄壁异型复杂结构，同时可进一步调控构件性能，成为了学术界和工程界研究的热点。对铝合金热冲压成形技术的研究成果和现状进行综述，重点介绍了近年来铝合金热冲压成形技术原理、典型工艺方法、变形强化机制和技术工程应用等四方面的研究进展，对以7系高强铝合金为代表的铝合金热冲压成形技术的研究现状与发展趋势进行了探讨和展望，旨在为铝合金热冲压成形技术的发展方向提供借鉴。

Under the development trend of high performance and light weight in the aerospace and automotive fields, aluminum alloys are more and more widely used, the strength of material is getting higher and higher, and the shape of components is becoming more and more complex, a higher challenge is presented to advanced forming manufacturing technology. Hot stamping technology utilizes the good plasticity of the material at high temperature to form a thin-walled and special-shaped complex structure at one time. Meanwhile,it can further control the performance of components, which has become a research hotspot in the academic and engineering circles. Therefore, the research achievements and present situation of the hot stamping technology for aluminum alloy were reviewed, mainly introduced the research progresses of aluminum alloy hot stamping technology principle, typical process method, deformation strengthening mechanism and technical engineering application in recent years. The research status and development trend of hot stamping technology for aluminum alloy represented by 7 series high strength aluminum alloy were discussed and prospected, aiming to provide reference for the development of hot stamping technology for aluminum alloy.
