“…The different flow properties between AZ31 and Al 1050 alloys are thought to cause plastic instabilities during the co-deformation of both alloys and as result the harder alloy (AZ31) undergoes a necking and finally cracks [23,24]. In fact, a better bonding was successfully obtained in the present study comparatively to Al 1052/pure Mg/Al1050 [18] and Al1060/AZ31/Al1060 [20] laminated composite fabricated in quite similar ARB conditions where the fracture and necking have been observed after 4 ARB cycles.…”

“…Based on thermo-mechanical processing, various techniques have been developed to elaborate multilayered composites through conventional deformation like hot rolling [6][7][8][9], hot pressing [10] and twinroll casting [11]. Recently, severe plastic deformation (SPD) processing such as equal channel angular extrusion (ECAP) [12], high-pressure torsion (HPT) [13] and accumulative roll bonding (ARB) [5,[14][15][16][17][18][19][20] have been successfully used to produce Al/Mg laminated composites. Particularly, ARB processing may be the most promising SPD process and bears a good potential for commercialization owing to its ability to produce ultra-fine grain (UFG) materials continuously [21].…”

“…The evolution of the microstructure at the bond interface of the Al/ Mg/Al multilayers and their mechanical properties have been widely investigated [5][6][7][8][9][14][15][16][17]. However, in the literature, very few studies do exist either on the crystallographic texture evolution [18,19] or on the microstructure features (interface features, grain size, grain boundary character distribution (GBCD) and dislocation density) of Mg and Al layers upon increasing ARB cycles [20].…”

The microstructure and texture of an Al1050/AZ31/Al1050 laminated composite fabricated by accumulative roll bonding at 400°C up to 5 cycles are investigated using Electron BackScatter Diffraction, neutron diffraction, microhardness measurements and tensile tests. EBSD analysis has shown that ARB processing led to microstructural refinement with equiaxed grain microstructure in AZ31 layers and to the development of elongated grains parallel to the rolling direction in Al 1050 layers. No new phases formed at the bond interface after the first ARB cycle while Mg 17 Al 12 and Mg 2 Al 3 phases appeared after subsequent cycles. During the ARB processing, a typical strong basal (0002) texture is observed in AZ31 layers along with a weak rolling texture showed in Al 1050 layers with a dominant Rotated Cube {001}〈110〉 component. The microhardness of Al1050/AZ31/ Al1050 laminated composite increased with increasing ARB cycles and almost saturated after five ARB cycles. The yield strength and ultimate strength increased gradually between 1 and 3 ARB cycles due to the strain hardening and grain refinement. They decreased with further increasing of the ARB cycles because of crack and failure of the Mg x Al y intermetallic compounds which developed during 4th and 5th ARB cycles. The deformation behavior of the laminated composite becomes rather similar to the behavior of AZ31 alloy that underwent a dynamic recrystallization during processing.

“…at persistent slip bands inclusions or grain boundary triple points. The delays in the crack initiation and their closure or even arrest after initiation are attributed to superficial compressive stress fields [9][10][11][12][13] . It is proved that shot peening, when using optimized parameters, can provide even a higher improvement of fatigue strength.…”

The effects of shot peening treatments on the microstructure and fatigue behavior of the teeth root in wet copper-based powder metallurgy friction plates were investigated and an efficient method for selecting optimal shot peening parameters for friction plates was proposed. Different experimental processes including microscopy observation, microhardness, roughness and X-ray diffraction measurements have been performed to characterize the treated surface of specimens. It is found that fatigue life of friction plates firstly increases and then decreases with the increase of Almen intensity, and the optimal fatigue life has improved over 55%. It is considered that both surface grain refinement and high residual compressive stress are the main ingredients responsible for the improved fatigue life. With further increase of Almen intensity, surface roughness of the teeth root gradually increases to a critical point, where rough peened surface may induce crack initiation due to stress concentration, and finally lead fatigue deteriorate.

Design of Architectured Materials Based on Mechanically Driven Structural and Compositional Patterning

Providing materials with an inner architecture that improves their mechanical and physical properties is a potent approach to materials design. Herein, the possibilities of such architecturing by means of severe plastic deformation (SPD) are discussed. Compositional and structural patterns caused by SPD processing can potentially improve the mechanical characteristics and physical properties of exemplary materials considered. The message to convey is that SPD opens up new opportunities with regard to producing materials with a multiscale structure. This can be achieved by virtue of the following effects associated with SPD: extreme grain refinement, whose level is governed by strain distribution; controlled self‐organization of the structure of multiphase materials; and anomalously fast mass transfer, which leads to the formation of new phases and various “reaction–diffusion” patterns. Furthermore, combining SPD with conventional metal forming, differential heat treatment, or 3D printing offers additional possibilities, which are considered in this article.
