- Abstract
By the metho ds of modern physical materials science the change in structural-phase state of AlCoCrFeNi high-entropy alloy (HEA) of nonequiatomic composition obtained by the metho ds of wire arc additive technology (WAAM) after irradiation by electron beams with energy density of 10–30 J/cm2, durality of 50 µs, frequency 0.3 s–1 is studied. In the initial state the alloy had a dendritic structure indicating the inhomogeneous distribution of elements. It is shown that electron beam processing forms the structure of high-velocity cellular crystallization with cell size of 100–200 nm, along boundaries of which the nano dimensional (15–30 nm) inclusions of the second phase enriched in Cr and Fe atoms are located.
