“…Laminated metal composites are composed of alternating layers of metals or alloys, bonding together at their interface, which have gained extensive attention because of their advantages such as improved fracture toughness, impact behavior, corrosion, wear, and damping capacity, [1,2] and have many applications in industrial sectors such as aerospace, automotive, and household applications. [3,4] To fabricate laminated metal composites, researchers have developed many methods such as hot roll bonding, [5,6] cold roll bonding, [7,8] cryogenic roll bonding, [9] accumulative roll bonding, [10,11] cross-accumulative roll bonding, [12,13] and explosive welding. [14,15] Roll bonding is the most widely used method to process all kinds of metallic composites.…”

“…Extensive researches on the mechanical properties and the microstructures of the Al/Cu, [23][24][25] Al/Ni, [26] Al/Ti, [9] and Al/Mg [27] composites have been conducted. Sandwich-like Cu/Al/Cu composites have several reasons for their wide applications such as their high conductivity, low density, and price competitiveness over copper and copper alloys.…”

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.

“…Therefore, cryogenic temperature (CT) SPD is developed to conquer the aforementioned limitation. Yu et al [14] found the ultimate tensile stress of Al/Ti/Al laminate sheets processed by cryogenic roll bonding was 36.7% higher than that by room-temperature roll bonding. By the way, edge cracks also appear in the latter, but the former is in good shape.…”

Conventional orthogonal machining is an effective severe plastic deformation (SPD) method to fabricate ultrafine-grained (UFG) materials. However, UFG materials produced by room temperature-free machining (RT-FM) are prone to dynamic recovery, which decreases the mechanical properties of UFG materials. In this study, the cryogenic orthogonal machining technique was implemented to fabricate chips that have an abundant UFG microstructure. Solution-treated Al-7075 bulk has been processed in cryogenic temperature (CT) and room temperature (RT) with various machining parameters, respectively. The microstructure, chip morphology and mechanical properties of CT and RT samples have been investigated. CT samples can reach a microhardness of 167.46 Hv, and the hardness of CT samples is higher than that of the corresponding RT samples among all parameters, with an average difference of 5.62 Hv. Piecemeal chip obtained under RT has cracks on its free surface, and elevated temperature aggravates crack growth, whereas all CT samples possess smoother surfaces and continuous shape. CT suppresses dynamic recovery effectively to form a heavier deformation microstructure, and with a higher dislocation density in CT samples, they further improve the chips’ hardness. Also, CT inhibits the formation of solute cluster and precipitation to enhance the formability of material, so that continuous chips are formed.
