FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy of heat resisting nickel alloys and can be used for the manufacture of heavy-duty elements of gas-turbine engines operating at high temperatures. The method of producing of articles from the granulated heat resisting nickel alloy includes filling, compaction and sealing of granules with their decontamination in a capsule, formation of an article by hot isostatic pressing (HIP) of the capsule into a finished article and its heat treatment. The capsule of a spherical shape is used, and before HIP the capsule is heated until the greatest plasticity of the capsule material and its upsetting is performed by pressing to the sizes with allowances for HIP.
EFFECT: improvement of mechanical properties of the article material is provided.
