FIELD: methods of treatment of metal materials for hardening them. SUBSTANCE: proposed method includes heating the blank to plastic deformation temperature and deforming it; metal materials are difficult- to-deform materials; deformation is performed by twisting. Material may be additionally subjected to compressive deformation. Blank is simultaneously subjected to twisting and compression. Titanium aluminide blank treated by this method; composition of alloy of this blank is as follows, atm-%: Ti, 47; Al, 3.7; (Nb, Cr, Mn, Si), 0.5B. EFFECT: enhanced strengthening of difficult-to-deform materials. 12 cl, 3 dwg |
