Microstructure evolution of copper/steel gradient deposition prepared using electron beam freeform fabrication

[Display omitted] •Copper and 304 stainless steel (SS) gradient materials were obtained using electron beam freeform fabrication (EBF3).•Nanoscale FeCu4 metastable phases were found in the deposition.•The microstructure evolution of copper/SS depositions were revealed. Additive manufacturing of copp...
