Abstract: Cu-Fe in-situ deformed alloys has high strength, high conductivity and broadband electromagnetic shielding performance. It is a new type of electromagnetic protection material with integrated functional structure and electromagnetic shielding performance. The research status of the broadband electromagnetic shielding properties of Cu-Fe in-situ deformed alloys was reviewed, and the influence rules and mechanisms of alloy elements, grain size and microstructure homogenization on the electromagnetic shielding properties of Cu-Fe in-situ deformed alloys were discussed, and its research and application were also prospected. It provides the necessary theoretical support for the research and development of structural and functional integrated Cu-Fe in-situ deformed alloys.
