| 摘要: |
| 铝合金因其轻质、高强、良好的加工性能以及优异的耐腐蚀性，在航天领域得到了广泛的应用。随着科技的进步和航天技术的发展，对铝合金材料的性能要求越来越高，促使铝合金材料不断向高性能、轻量化的方向发展。热渐进成形作为一种先进的板料成形技术，为航天用铝合金零件的制造提供了新的解决方案，并获得了当今学者的广泛关注。根据渐进成形加热方式不同，总结了近年来典型的加热方法为电加热、激光加热、电磁感应加热。在此基础上，综述了铝合金热渐进成形极限方面的研究，并总结了多种工艺参数对材料成形极限的影响规律。 |

| Abstract: |
| Aluminum alloy has been widely used in the aerospace field, because of some advantages, such as light weight, high strength, good processing performance, and excellent corrosion resistance. With the development of aerospace technology, the performance requirements for aluminum alloy materials are higher, which promotes the continuous development of aluminum alloy materials in the high-performance and lightweight direction. As an advanced sheet metal forming technology, the hot incremental forming process provides a new solution for the manufacture of aerospace aluminum alloy parts, and this technology has received extensive attention from scholars. During the hot incremental forming process, the three typical methods, such as electric heating, laser heating, and electromagnetic induction heating, are investigated. On this basis, the investigational advance of the hot incremental forming limit of aluminum alloy is investigated, and the effect of process parameters on the material forming limit is also investigated in detail. |
