“…Qaudir et al [42] investigated single rolling of pure Al at 300 • C and found that increasing R resulted in bonding toughness enhancement especially for those reductions greater than 47%. Similar findings were reported for Al-Cu by Yousefi et al [36] and for Al/brass by Naseri et al [43].…”

Different manufacturing processes can be utilized to fabricate light-weight high-strength materials for their applications in a wide spectrum of industries such as aerospace, automotive and biomedical sectors among which accumulative roll bonding (ARB) is a promising severe plastic deformation (SPD) method capable of creating ultrafine grains (UFG) in the final microstructure. The present review discusses recent advancements in the ARB process starting with the ARB basics, intricacies of the underlying mechanisms and physics, different materials, surface and rolling parameters, and finally its key effects on different properties such as strength, ductility, fatigue, toughness, superplasticity, tribology and thermal characteristics. Moreover, results of recent computational investigations have also been briefed towards the end. It is believed that ARB processing is an emerging area with tremendous opportunities in the industrial sector and ample potential in tailoring microstructures for high-performance materials.

“…The Cu/Al interlayer bonding quality affected by the rolling temperature is also a significant factor on the mechanical properties. It has been extremely reported that the deformation parameters, such as rolling reduction, rolling temperature, the friction condition, heat treatment, rolling strain rate, and so on, have great effects on the bound quality. However, there are few reports about the investigation on the mechanical properties of Cu/Al composites subjected to cryorolling, which have a broad application prospect as potential structure materials .…”

“…With higher rolling temperature, the residual stress near the AlCu intermetallic layer reduces, and its distribution becomes more uniform. According to the film theory, [31,32] the brittle surface layer is broken due to the rolling pressure. In addition, the brittle surface layer is easier to break with lower rolling temperature.…”

Herein, sandwich‐like Cu/Al/Cu composites are fabricated by hot rolling (300 °C), cold rolling (25 °C), cryorolling (−100 and −190 °C), respectively. Tensile tests are conducted and the fracture surfaces of both the Al and Cu sides are examined using scanning electron microscopy (SEM) for fractography and SEM‐based energy‐dispersive analysis. The microstructure of the composites is evaluated by optical microscopy and SEM. Results reveal that the highest ultimate tensile strength and the best ductility of the composites have been achieved using cryorolling of the rolling temperature −100 °C. Finally, discussion on grain size, bonding quality, and the thickness of the intermetallic layer between Cu and Al layers on the mechanical properties of the sandwich‐like Cu/Al/Cu composites is focused.

“…The friction coefficient between the billet (inner, outer pipe) and drawing the die and plug is set as 0.12 because dry lubricant is used. The plug and billet (inner pipe, outer pipe) used sticking conditions (Karnezis and Farrugia, 1998;Neves et al, 2005;Palengat et al, 2013). The measured surface roughness was converted into the friction coefficient using Eq.…”

Abstract. Pipes applied to marine plants are used in deep-sea environments; therefore, they must be resistant to high pressure and corrosion. Because it is difficult to satisfy both of these factors in a single pipe, studies on a double-layered pipe are continuously being performed. An outer pipe should be made of carbon steel, with high pressure resistance, and an inner pipe should be made of stainless steel, with high corrosion resistance. A pipe formed by combining these two pipes is called a lined pipe. The shear strength of the lined pipe is an important factor because pipe cracking can occur due to stress concentration when two pipes are separated by bending or high pressure. Therefore, various processes have been applied to increase the shear strength. In this paper, we investigate the effect of the surface roughness of the bonding interface on the shear strength. Surface roughness is in units of micrometers, and it cannot be used for finite element method (FEM) analysis. Therefore, surface roughness should be converted into a friction coefficient to perform FEM analysis. The effect of surface roughness on shear strength was studied in the relationship between the results of pressure from FEM analysis and the shear strength test.
