Annotation
The work provides a retrospective analysis of scientific publications describing the development of theoretical ideas about the processes of producing products using the extrusion method. The main attention is paid to methods for theoretically describing the extrusion of highly filled plastic compositions consisting of three phases: solid
particles of the main phase, soft plasticizer and gas phase. Such compositions include plasticized metal, carbide and ceramic powders, which in their physical and technological properties differ significantly from viscous liquids, cast metals and pure powders. An analysis of publications shows that a general theory of deformation of such media has not yet been constructed.
Key words
extrusion, visco-plastic medium, plasticized powder, theory of deformation, powder metallurgy
