FIELD: alloy metallurgy.
SUBSTANCE: invention relates in particular to the methods for obtaining a homogeneous and defect-free microstructure in aluminum-based alloys by laser melting, including using additive technologies, and can be used in the space industry, transport engineering, resource-saving and energy-saving technologies. The method of obtaining a homogeneous and defect-free microstructure in aluminum alloys by means of laser melting consists of complex alloying of the alloy with additives, heating the processing area to temperatures of 350-480°C. After laser melting of each layer, additional processing is carried out with a laser beam at a temperature of 0.9-0.95 Tm of the alloy.
EFFECT: creation of a method for obtaining a homogeneous and defect-free microstructure during crystallization after laser melting in aluminum-based alloys.
