FIELD: aerospace technology.
SUBSTANCE: invention relates to a method for manufacturing aluminum alloy parts of the Al-Mg-Sc system and can be used for the production of parts and assemblies of aviation and rocket and space systems. Parts are obtained by selective laser fusion from aluminum alloy powders of the Al-Mg-Sc system. Laser fusion is carried out inside a sealed chamber in a protective gas environment with the following technological parameters: laser radiation power from 200 to 300 W, scanning speed from 700 to 800 mm s, scanning step from 0.13 to 0.17 mm, layer thickness 50 mcm.
EFFECT: production of parts with low porosity, with high mechanical properties and a low level of residual stresses.
