摘要

In this paper, the influence of flyer strength on the deformation behavior, interface morphology, and mechanical properties of aluminum/steel EMPW joints is investigated. A comprehensive analysis is conducted to evaluate the deformation of the flyer within the effective welding area, interface characteristics, and mechanical properties of the resultant joint. The flyer deformation progressively intensifies, exhibiting a wave-like pattern that mirrors the microscopic interface deformation of the joint. At a flyer strength of 239.5 MP, the joint achieves an optimal balance of strength, hardness, and flyer deformation, demonstrating the best mechanical properties with a maximum load of 4.39 KN and an IMC layer thickness of 3.26 μm. The aluminum–steel EMPW interface evolves from flat to wavy with protrusions and eventually forms a continuous wavy transition layer as flyer strength decreases. Fe2Al5 and FeAl3 predominate in the composition of the transition layer, according to XRD and EDS studies.
