| Titanium alloy is the main lightweight structural material in aerospace field. It has high strength, but it is not easy to form and has high springback. The development of electromagnetic forming technology provides a new and effective way for precise and efficient forming of titanium alloy parts. In this paper, the application of electromagnetic forming technology in titanium alloy sheet forming were summarized from three aspects of high-speed plasticization, forming process, and numerical simulation. The problems existing in the electromagnetic forming of titanium alloy sheet were briefly analyzed based on the authors' research experience. On this basis, the formability and deformation mechanism of materials under electromagnetic forming technology were emphatically summarized, and then the research progress of electromagnetic bulging and flanging technology of titanium alloy was summarized, and the multi-physical field coupling simulation technology of electromagnetic forming of titanium alloy was introduced. Finally, the future development of electromagnetic forming technology of titanium alloy sheet was prospected. The results show that electromagnetic forming technology can improve the formability of titanium alloy sheet and the high conductivity low strength plate with thickness close to skin depth is a high quality driver plate. In order to further promote the application of electromagnetic forming technology in titanium alloy sheet forming, it is required to develop higher strength coils and better driving methods. |
