ADDITIVE MANUFACTURING FOR ELEVATED-TEMPERATURE DUCTILITY AND STRESS RUPTURE LIFE

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to the manufacture of a component of a gas turbine engine from a metal powder. Method includes additive manufacturing of the component and its heat treatment. Additive manufacture of the component is conducted in a molding chamber into which a carburizing gas is introduced, the heat treatment of the component obtained by the additive manufacture is carried out with the deposition of carbides at the grain boundaries.;EFFECT: it is ensured the manufacture of a gas turbine engine component operating at high temperatures.;6 cl, 6 dwg
