FIELD: powder metallurgy.
SUBSTANCE: invention relates in particular to the production of metal products from powder TRIP steel. A workpiece is pressed from powder TRIP steel under conditions of intense plastic deformation by compression under a pressure of 6-8 GPa with simultaneous torsion. The angle of rotation of the workpiece around its axis during torsion is from 10° up to 40°. The resulting workpiece is subjected to sintering.
EFFECT: high level of mechanical properties of products made from powder TRIP steels.
