FIELD: metallurgy.
SUBSTANCE: in machine for laser synthesis powder mixture is placed from initial components for SVS, which are taken in accordance with stoichiometric composition of target materials that are synthesised directly prior to laser radiation. Then laser treatment of layerwise molded volumetric article is carried out, during which SVS takes place in diffusion mode, and then the article is taken out of the machine. Process of articles production is performed in magnet, electric or ultrasonic fields. Laser radiation in the process of synthesis is dosed in accordance with minimum necessary level of energy required for performance of local SVS process in the spot of laser radiation.
EFFECT: method allows to produce articles with high strength and improved functional properties and to increase output of proper articles.
