The paper presents the results of structure studies and mechanical tests of samples with gradient structure obtained on the basis of pure copper and Ni80Cr20 nickel-based alloy using double wire-feed electron beam technology. The obtained data testify to the high strength of structural gradient zone in the majority of the investigated specimens. The formation of defects in the form of cracks and a decrease in the strength of the structural gradient zone is noted for a number of samples. The material of the gradient zone exhibits sufficiently significant heterogeneity of structure with the presence of large fragments of nickel-based alloy in copper matrix.
