The structure of the contact zone of the surfacing-substrate subjected to electron-beam processing

Using scanning and transmission electron microscopy, the analysis of structure, phase elemental composition contact zone system coating (high-entropy FeCrCoNiMn alloy)-substrate (5083 alloy) after electron-beam processing was performed. The formation a multiphase, multielement submicro- nanocrystalline structure has been established. high-speed cellular crystallization in layers adjacent to substrate is revealed, lamellar crystals central region also found. Keywords: zone, high-entropy alloy, wire-arc additive manufacturing method, 5083 aluminum pulsed beam, composition, structure.. structure.
