FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and can be used for production of metal products. A shaped metal billet with irregularities on the surface is obtained by using additive production. Then billet irregularities are smoothened with power source sufficient to produce billet suitable for processing. Smoothing involves smoothing with an electron beam, melting with a pulsed lamp, melting with a laser, arc melting, laser ablation and combinations thereof, as well as heating at least a portion of one formation of continuously deposited layer of fused metal. Further, shaped metal billet is processed to produce finished processed article.
EFFECT: improved mechanical properties of the obtained articles.
