| Popis: | The paper studies the structure and mechanical properties of the copper alloy based on a Cu–Al–Si–Mn system, produced by wire-feed electron-beam additive manufacturing (EBAM). Energy dispersive X-ray spectroscopy on the scanning electron microscope is carried out to investigate the microstructure and composition of the obtained copper alloy specimens. The tensile strength and microhardness of the alloy specimens are studied to determine its mechanical properties. It is shown that the structure of the manufactured material consists of the κ-phase dendrite grains and the γ-phase layers. According to static tension tests, the copper alloy possesses isotropic hardness and anisotropic ductility. Its hardness values also indicate the anisotropy of mechanical properties due to, mainly, a two-phase structure and nonuniform distribution of microhardness in the bulk of the Cu–Al–Si–Mn system-based copper alloy deposited using wire-fed EBAM. |
