The Cube Recrystallization-Texture Related Component in the β-Fiber Rolling-Texture FCC Metals

Abstract

The cold-rolling texture of fcc sheet metals with medium to high stacking fault energies is known to consist of the brass {011}<211>, Cu {112}<111>, Goss {011}<100>, S {123}<634>, and cube {100}<001> components. The recrystallization (Rex) texture of cold-rolled Al, Cu and their alloy sheets is well known to be the cube texture. The 40°<111> orientation relationship between the S and cube components, which has been taken as a proof of the oriented growth theory, has made one believe that the S orientation is responsible for the cube Rex texture. The oriented growth theory is claimed to be associated with grain boundary mobility anisotropy. However, some data indicate the Cu component is linked with the cube component. There is no 40°<111> orientation relationship between the Cu and cube components. The strain-energy-release-maximization model (SERM), in which the strain energy due to dislocations is importantly taken into account, suggests that the Cu and S components in the rolling texture are linked with the cube and ~{031}<100> components in the Rex texture, respectively.

Formability of the 5754-Aluminum Alloy Deformed by a Modified Repetitive Corrugation and Straightening Process

“…Quantification of the texture fraction volume was carried out in order to track the evolution of the texture components as a function of the number of RCS passes. The previous observations indicate that the sample had a mixed texture of β-fiber and Goss; no significant cube texture was found, but a fiber connecting S and cube was observed, this is already mentioned as a possible path of recrystallization towards Cube [30]. This fact agrees well with the sample thermomechanical history, as the sample was rolled (generating the β-fiber) and then annealed, producing S-Cube fiber.…”

Mechanism of misorientation development within coalesced martensite

“…Given that the habit plane is not a close packed plane of austenite, it requires a combination of slip systems to accommodate the transformation shear (we have neglected the smaller volume change due to transformation). Using the well established Taylor theory for the operation of multiple slip systems to account for an arbitrary plastic deformation,28 it was found that the simultaneous operation of the slip systems and with the shear strain due to the former being five times that of the latter can accommodate the shape deformation of martensite. The full description for the calculation is available in Ref.…”

On the Role of Grains in Plastic Deformation and Low Cycle Fatigue of Polycrystalline Metal

“…Those parameters of anisotropy can be defined for a grain as well as for polycrystalline metal [1]. Those parameters are also important in relation to the texture analysis [5,6].…”
