“…There is also < 111 > texture variation along the depth, but it is weaker. These observations are consistent with other reports and simulations on surfaces processed by attrition or peening [119][120][121].…”

“…Similarly, the usage of impacting particles to produce a gradient often come with the assumption of stochastic impacts and deformation, however the deterministic, periodic nature of the method (e.g. surface mechanical attrition treatment (SMAT) or SMAT in a SPEX mill jar) clearly result in dominant texture formation [118][119][120][121].…”

“…It can be expected that the texture will affect the mechanical behavior of each layer along the depth and provide additional mechanical incompatibility effects, however, since the texture gradient occurs concurrently with the grain size gradient, it is challenging to decouple its effect on the mechanical behavior with experimental methods alone. Simulation efforts, such as those reported in [121,122] are necessary to provide clarity on what textures may form based on the nature of the driving deformation method, and more so, the contributions to the novel mechanical responses that are observed.…”

Heterostructured materials are an emerging class of materials with superior performances that are unattainable by their conventional homogeneous counterparts. They consist of heterogeneous zones with dramatic (> 100%) variations in mechanical and/or physical properties. The interaction in these hetero-zones produces a synergistic effect where the integrated property exceeds the prediction by the rule-of-mixtures. The heterostructured materials field explores heterostructures to control defect distributions, long-range internal stresses, and nonlinear inter-zone interactions for unprecedented performances. This paper is aimed to provide perspectives on this novel field, describe the state-of-the-art of heterostructured materials, and identify and discuss key issues that deserve additional studies. IMPACT STATEMENT This paper delineates heterostructured materials, which are emerging as a new class of materials with unprecedented properties, new materials science and economic industrial production.

“…Otherwise, the loading conducted at 45° RD exhibited the smallest increase in the flow stress, 86 MPa, being this behavior opposite of that observed under monotonic loading in tensile (Figure 5a). These differences in macroscopic mechanical results suggest the occurrence of crystallographic modifications after the strain path change as observed by Gracio et al 7 using pure Al alloys and Wang et al 21 .…”

“…Changes in the strain path amplify dislocation activity in secondary slip systems that tend to persist inoperative prior to the onset of these transients. Furthermore, the crystallographic textures tend to become sharp-defined before the onset of transients 21 . These structural changes can be related to the increase in the flow stress and the subsequent decrease and the occurrence of a transient stage in the normalized work-hardening rate observed for AISI 409 steel during the rolling/shear loading.…”

The mechanical behavior of metallic materials depends on several variables, such as the material structural characteristics, the process parameters, the temperature, the strain rate and the anisotropy features due to strain paths in different metal forming operations. Considering the last one, the effect of shear direction loading on the work-hardening after the rolling/shearing loading of a ferritic stainless steel, AISI 409, was investigated in this work. The annealed AISI 409 sheets were predeformed by cold rolling up 0.19 effective strain and then sheared at three different directions: at 0°, 45° and 90° from the original rolling direction. The samples were characterized through tensile, shear and Vickers microhardness tests while the study of crystallographic texture was performed using the electron backscatter diffraction (EBSD) technique. The work-hardening behaviour of the material was analyzed considering the work-hardening rate and the Hollomon work-hardening exponent after each strain path change applied to the AISI 409 steel. The results indicated the presence of preferential crystallographic orientation and the occurrence of transients on the work-hardening rate mainly for the sample sheared at 45° from the original rolling direction due to structural arrangements assumed by the AISI 409 steel after the strain path changes.
