Controlling the textures of the metal strips via the continuous confined strip shearing (C2S2) process

Abstract

A new concept process, a so-called as C2S2 process based on equal channel angular pressing, for fabricating the Al alloy sheets with a high formability is introduced. The C2S2 machine was designed so that it can feed the metal strip in a continuous manner at a relatively high speed in the range of similar to 20 m/min. A significant amount of the sheer deformation could be achieved by passing the sample through the ECAP die with Phi = 120 degrees. The pole figures were calculated both to demonstrate the evolution of the textures of the 1050 Al alloy sheets and to elucidate the feasibility of the proposed process as a means for enhancing the formability of the metal strips.
