摘要：
In this work, the characteristics of surface morphology and structure of experimental samples of nickel-based alloy and copper nozzles manufactured by the electron beam additive method have been studied. It is found that the grain boundaries on the outer sample surface are oriented at different angles relative to the substrate due to uneven heat dissipation during printing. It is found that 3D printing in a non-optimal temperature regime produces a highly heterogeneous structure within the material layer. A curvilinear boundary zone is observed in which different structural phase components are formed, including solid solutions and mechanical mixtures.
