FIELD: powder metallurgy, possibly manufacture of powdered parts subjected to loading. SUBSTANCE: method comprises steps of cold pressing, heating, hot compaction of blank and subsequent three dimensional deforming. Hot compaction is realized until achieving remaining porosity 1-2%; subsequent deforming is performed at process of further pressing stage. EFFECT: elimination of remaining porosity, enhanced mechanical properties of powdered products due to improved joining of contact surfaces.
