FIELD: metallurgy.
SUBSTANCE: method includes billet deposit and further torsion ensuring shear deformation. The billet deformation is made in Bridgman peens with specific pressure 3-6 GPa application. The movable peen is rotated relatively to its axis with speed 0.02-1.5 rpm. During the peen rotation the cyclic change of the specific pressure is performed by 10-20% of current value with rate 0.1-1.5 of specified speed of the peen rotation.
EFFECT: cyclic load application at intensive plastic torsional deformation ensures uniform microstructure and increases strength and microhardness of the billet material.
