Abstract

Conditions are analyzed for implementation of helical extrusion of iron-nickel alloy billets with the aim of forming a submicrocrystalline structure within them. Properties are provided for heat-resistant iron-nickel alloys ÉP718-ID (KhN45MVTYuBR ID) and Inconel 718. Two alternative versions are considered for deformation of this type at high and low temperatures. A regime is suggested for helical extrusion of small billets.
