FORGING IN THE OPEN STAMP WITH SEPARATE PASSAGES OF DIFFICULT FOR FORGING AND SENSITIVE TO THE TRAJECTORY OF DEFORMATION OF ALLOYS BASED ON TITANIUM AND BASED ON NICKEL Russian patent published in 2017 - IPC B21J1/02 B21J5/02 C21D7/10 C22F1/00 

FIELD: metallurgical engineering.

SUBSTANCE: forging is performed by the heated blank on the press in an open stamp in the first forging direction to the plasticity limit of the blank material. This forging is then repeated until a total degree is obtained sufficient to initiate grinding of the microstructure. Then the blank is rotated through an angle and forged in the second forging direction until the overall degree of deformation in the second forging direction is sufficient to initiate the grinding of the microstructure. The step of turning and the forging step in the third and, optionally, one or more additional forging directions are repeated. Repetition is carried out until total degree of deformation will be obtained in the entire volume of the blank, sufficient to initiate the grinding of the microstructure. The blank is not rotated until a general degree of deformation sufficient to initiate grinding of the microstructure is obtained in the third direction and any one or more additional directions.

EFFECT: increase of efficiency of initiation of the mechanism of grinding of microstructure.
