The paper present the results of numerical simulations of the alternate indirect extrusion and multiaxial compression process, performed using commercial software designed for the thermomechanical analysis of plastic working processes, Forge 2009. The novel method of alternate indirect extrusion and multiaxial compression, proposed by the authors, is characterized by the occurrence of strain states in the material being plastically worked, which are similar to those occurring in the equal channel angular pressing and cyclic extrusion compression processes.
