FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular, to the manufacture of parts by layer-by-layer laser fusion of metal powders of titanium-based alloys. It can be used in the aviation, space, and energy industries. The metal powder is applied to the substrate in layers with a thickness of 60-100 mcm. Selective fusion is carried out by a laser beam with a diameter of 100-250 mcm, a volumetric energy density in the range of 35-75 J/mm3 in a flowing argon medium.
EFFECT: reduction in the volume fraction of pores and a reduction in the part manufacturing time is provided.
