“…Wu et al (2015) reported that the lamellar structure of pure titanium would lead to the same strength as that of the fine-grained structure, as well as to the same elongation as the coarse-grained structure. Similarly, the IF steel, as reported by Zhang et al (2017), would also demonstrate good mechanical properties attributing to the lamellar structure. In previous reports (Koyama et al, 2011;Gutierrez-Urrutia and Raabe, 2012;Renard and Jacques, 2012;Shterner et al, 2014Shterner et al, , 2016, the formation of deformed twins could inhibit the movement of dislocations, as well as reduce the average free path of dislocations, while producing a dynamic Hall-Petch effect (Grässel et al, 2000;Karaman et al, 2000;Bouaziz and Guelton, 2001;Allain et al, 2004a); therefore, TWIP effect significantly improved the comprehensive mechanical properties.…”

A composite high manganese structure comprising recovered and recrystallized structures was prepared using a single-phase austenitic Fe-30Mn-0.14C-7Cr-0.26Ni steel by cold rolling and annealing. The yield strength and elongation of the composite increased simultaneously, when the tensile temperature decreased from room temperature (RT) to low temperature (−180 • C). The composite structure exhibited a good combination of strength and ductility at RT and −180 • C. The notable mechanical properties at low temperature can be attributed to the enhanced strain-hardening capability via introducing multiple deformation mechanisms in the composite structure.

“…Pioneering studies have shown that pure Ti with a heterogeneous lamella structure can unite UFG strength and coarse-grain ductility 19 . Such combinations of high strength and good ductility were also demonstrated recently in an interstitial free (IF) steel 20 and a Mn steel 21 . Therefore, the present study is aimed to produce a layered bimodal grain structure in Mg alloys and address the effect of bimodal structures on mechanical properties.…”

AZ31 Mg alloy was processed by accumulative roll-bonding (ARB) and hot rolling (HR), respectively, followed by annealing. Layered bimodal structures characterized by an alternative distribution of fine-grained layers and coarse-grained layers were obtained in the ARB samples, while mixed bimodal structures were achieved in the HR samples. The ARB samples have superior combinations of high strength and good elongation compared to the HR samples, indicating a clear effect of layered bimodal structures on mechanical properties of the alloy. The strength of the ARB samples is related to the grain size; while the ductility is attributed to the activity of non-basal slip and the strong backstress.

“…It is however unknown whether significant local residual stresses develop between recrystallized grains and their surrounding matrix during recrystallization. This knowledge is important for understanding the mechanical properties of partially recrystallized materials [59,60] and may be critical for the microstructural evolution during subsequent annealing or deformation.…”

Synchrotron 3D X-ray Laue microdiffraction, available at beamline 34-ID-E at Advanced Photon Source in Argonne National Laboratory, is a powerful tool for 3D non-destructive mapping of local orientations and strains at sub-micron scale in the bulk. With this technique, it is possible to study local residual stresses developed during manufacturing or while in service due to interactions between, for example, different phases and/or grains with different orientations in materials containing multiple or single phase(s). Such information is essential for understanding mechanical properties and designing advanced materials, but is largely non-existent in the current generation of materials models. In the present paper, the principle and experimental set-up of the 3D microdiffraction are introduced, followed by a description of a method for quantification of the local plastic deformation based on high-angular-resolution orientation maps. The quantification of local residual stresses in two model materials, ductile cast iron (two phases) and partially recrystallized pure nickel (single phase), using 3D microdiffraction will then be presented. The results show that 3D microdiffraction is important for understanding the origin of local residual stresses and to relate them to the microstructural evolution. Finally, the limitations of the 3D microdiffraction on the current generation synchrotron source and new possibilities after the synchrotron upgrade are discussed.
