FIELD: powder metallurgy. SUBSTANCE: method involves heating and isothermal pressing the material through differently heated equal-section channels arranged at an angle of 90 deg and through inclined channel with a die. Inclined channel is set at an obtuse angle of 2 θ = 180-150 deg to the horizontal one. Drawing in the die is adjusted within 2.45-13. Total deformation in the inclined channel is determined within a range of 3.2-13 while the value of drawing in the die at a current value of inclination angle q is determined from the relation submitted in the description. Deformation temperature is stabilized by adjusting the outflow temperature conditions in the inclined channel by means of microcomputer. EFFECT: improved operating and functional characteristics. 9 cl, 2 dwg, 5 tbl
