摘要

Four samples of Inconel 718 superalloy are produced by wire-feed electron beam additive manufacturing (EBAM). The samples are formed under different heat input conditions by varying the additive printing speed and the electron beam current. It is shown that the macrostructure has several characteristic zones differing significantly throughout the entire height of the additively produced samples. The microstructure, consisting of dendritic arms and carbides located between them, varies for each selected process parameter set. With a decrease in the resulting energy input, the dendritic core is mainly refined. The formation of strengthening phases and carbides is uneven throughout the height of the additively produced samples, leading to unstable mechanical properties.
