The products produced using additive techniques (with no use of conventional production techniques) are of high priority for aerospace and aircraft engine building. The possibility of using domestic heat-resistant powders in additive processes is investigated. It is shown that domestic heat-resistant materials are promising for additive techniques. It is found out that domestic powders have a wide size range and the defects, such as satellites and chips, are detected on the powder granule surface. It is revealed that the surface morphology and microstructure of particles are typical for heat-resistant nickel alloys. It is established that heat-resistant nickel-based EP741p alloy (SE USSI) can be used in additive techniques.
