FIELD: additive technologies.
SUBSTANCE: invention relates in particular to a method for producing workpieces from a heat-resistant nickel alloy by selective laser melting. Can be used for the manufacture of functional blanks for parts and assembly units of the combustion chamber of an industrial engine. Before selective laser melting of heat-resistant nickel alloy powder “ХН58МБЮ-ИД”, the deformation of the workpiece and distortions in generative processes are predicted based on the finite element method of a digital model of the technological process of selective laser melting. Selective laser fusion is carried out at laser power from 148 to 331 W, scanning speed from 480 to 660 mm/s, scanning step from 0.11 to 0.14 mm and layer thickness from 50 to 60 mcm.
EFFECT: it is possible to obtain workpieces with high mechanical characteristics, high material density and low residual stresses.
