Abstract
The paper presents first results of studying samples of high-temperature carbide hardened intermetallic Ni–Al–Ta–C alloys manufactured by selective laser melting. It is shown that the right technological parameters of atomization ensure correct metallurgical processes. The parameters of selective laser melting were determined, which made it possible to obtain a dense structure of the synthesized material.
