Development of SPD continuous processes for strip and rod production

Grain refinement upon the severe plastic deformation (SPD) at low temperatures (below the recrystallization temperature ) and an unusual improvement the properties of such materials are shown reliably. However, the industrial application is limited due to the absence of effective continuous SPD processes. The potential of development of continuous SPD processes based on the equal channel angular pressing (ECAP) process from one side and continuous extrusion (such as “conform”, “linex” and “extrolling”) or drawing processes from another side is considered. Existing continuous SPD processes for strip, rod and wire production such as Conshearing, Continuous confined strip shearing (C2S2), different schemes of Conform – ECAP and Equal Channel Angular Drawing, are analyzed.
