METHOD FOR DEFORMATION OF AXISYMMETRICAL BILLETS Russian patent published in 1998 - IPC

Abstract RU 2113301 C1

FIELD: plastic metal working; may be used in manufacture of rods and pipes from difficult to deform material. SUBSTANCE: method for deformation of axisymmetrical billets from composite material reinforced by dispersion includes deformation in dies with conical working channel. In this case, permissible drawing is determined by the conditions to prevent postdeformation failure caused by residual stress by the formula given in the invention description. EFFECT: higher strength, increased service life and service stability of resulting articles. 1 dwg
