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

A new concept process, a so-called as C2S2 process based on equal channel angular pressing, for fabricating the A1 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 ∼...

Summary:A new concept process, a so-called as C2S2 process based on equal channel angular pressing, for fabricating the A1 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 ∼20 m/min. A significant amount of the shear deformation could be achieved by passing the sample through the ECAP die with Φ = 120°. The pole figures were calculated both to demonstrate the evolution of the textures of the 1050 A1 alloy sheets and to elucidate the feasibility of the proposed process as a means for enhancing the formability of the metal strips.
