Texture evolution of an Fe–Ni alloy sheet produced by cross accumulative roll bonding

“…In CARB case, α = 0.5 corresponds to an intermediate situation which is sufficient to modify the activated slip systems, as some previous works on CARB suggested . Such a case results in a faster refinement of the microstructure (Figure ) and to a larger yield stress (Figure ).…”

“…All these studies evidenced a higher strength after CARB than after ARB. Up to date, only a very few studies concerned the texture evolution after CARB . On the one hand, a first work on an Invar (Fe–36%Ni) showed a cyclic texture and the appearance of a new (H {012}<221>) component.…”

Accumulative roll bonding (ARB) is performed at room temperature on an aluminum composite up to five rolling cycles, using two different paths: the conventional one (ARB) and the cross ARB (CARB) one consisting of a 90 rotation of the rolling direction before each rolling pass. The microstructure is refined faster by CARB than by ARB occasioning higher yield strength of the elaborated samples. Besides, CARB has the ability to delay the loss of stratification of the composite. The resulting textures are different: while ARB promotes typical rolling components (Brass {011}<211>, Goss {110}<001>, Dillamore {4 4 11}<11 11 8>), S {123}<634>), CARB promotes the ND-rotated Brass {011}<755> instead of Brass together with the S and Dillamore components. A Visco-Plastic Self-Consistent (VPSC) simulation highlights that the ND-rotated Brass had Brass and S components for origin. The ND-rotated Brass presence in the texture promotes a better mechanical isotropy of the composite sheet.

“…[91] In addition, the CARB process can also reduce the plastic anisotropy of the sheets. [92] Ruppert et al [93] compared mechanical properties of ARB-processed and CARB-processed sheets. They found that the strength of CARB-processed Al 6014 samples exceeds the strength of the ARB-processed samples.…”

Interest in ultrafine-grained (UFG) materials has grown rapidly in past 20 years. This review focuses on the application of special rolling techniques for improvement of the mechanical properties of UFG metal sheets. These techniques include asymmetric rolling, cryorolling, asymmetric cryorolling, cross-accumulative roll bonding, and skin-pass rolling. The techniques also include a combination of processes such as equal channel angular press and subsequent rolling, combined high-pressure torsion and subsequent rolling, as well as combined accumulative roll bonding and subsequent asymmetric rolling. We also discuss the main mechanisms leading to improvement in the ductility of UFG materials related to the special rolling techniques. properties of ultrafine-grained (UFG) metal sheets.
