Abstract

Data are provided for a new process achieving a greater degree of plastic deformation by reverse extrusion in bulky billets with the aim of forming a fine-grained structure. An algorithm is developed for loading stages of billets providing uniform accumulation of the degree of deformation throughout its volume. Data are provided for metal kinematic flow obtained by simulating reverse extrusion in Deform. New technology is proven by experiment using copper M1. Microstructure is studied after achieving a degree of deformation of 5.5–6. The possibility of obtaining a bulky billet with a grain size of 5–8 μm is demonstrated.
