Microstructure, Texture, and Mechanical Properties of Laminar Metal Composites Produced by Accumulative Roll Bonding

The paper aims to summarize the research on Laminar Metal Composites produced by Accumulative Roll Bonding. After some notes on the general subject, frequent material combinations and the issue of bonding are addressed. Then, the evolution of microstructure, texture, and mechanical properties typically observed in such materials is briefly summarized. Furthermore, the crucial aspect of layer continuity is discussed. In the main part, detailed experimental insight is provided for three representatives of different structural developments, namely Al2N/Al5N, Cu/Nb, and Ti/Al. The chosen systems represent different levels of component dissimilarity, as Al2N/Al5N is a combination of the same face centered cubic metal with varying purity while Cu/Nb and Ti/Al are combinations of face centered cubic with both body centered cubic and hexagonal close packed metals, respectively. As the layer thicknesses span different ranges, the composites also illustrate both the opportunities and experimental challenges of ARB Laminar Metal Composites.bonding (in the following, those processes will be referred to "ARB"), often supplemented by annealing and rolling steps. Naturally, a high percentage of the scientific attention regarding LMCs is bestowed on Al alloys, for example, [7,25,[43][44][45][46][47][48][49][50] whose assets are excellent formability and corrosion resistance while being low in both weight and price.Al alloys are frequently combined in order to improve specific properties, for example, [51][52][53][54][55] A strong but corrosion susceptible Al alloy of series 2xxx, for example, benefits from the combination with a less strong but corrosion resistant alloy of series 6xxx. [50] Likewise, in LMCs of series 5xxx and 6xxx, both surface quality and weldability are improved due to the reduction of the PLC-effect [53] and hot cracking, [55] respectively.By combining Al with both Fe [56][57][58] or Cu, [45,59] the magnetic properties of the former and the electrical properties of the latter can be used to produce LMCs with potential in microelectronics and in electrical power industry, [60] respectively. Other components in LMCs with Cu are Ag, [61] Zn, [62] both Zn and Al, [63] and both Al and Ni. [64] Nb receives major scientific attention due to its superconducting properties, which work especially well in a finelayered structure with Cu or Al, [65] which are chosen for their low solubility in Nb and the absence of mutual intermetallics. In contrast, other LMCs are produced especially for intermetallic transition, for instance Al/Fe, [57,58,66] Al/Mg, [43,44] Al/Ti, [67][68][69][70][71] Al/Ni, [72,73] Ti/Nb, [74] or Ti/Al/Nb. [74] When high specific strength in combination with sufficient formability and ductility is the foremost requirement, Al is often combined with high-strength partners such as steel, for example, [66,75] Mg, for example, [46,76,49] Ti, for example, [67][68][69]74,[77][78][79][80][81][82][83][84][85][86] as well as both Mg and Ti. [87] Furthermore, Ti is paired with Fe, [88,89] Cu, for example, [90,...

“…For AZ31 under this condition, they found that the temperature of 300 • C and friction coefficient of 0.35 compromised ARB processing parameters to achieve the highest homogeneous strain distribution accompanied by no significant grain growth. Similar FE investigations on the affecting parameters on deformation behavior during roll bonding were also carried out by Hosseini et al [148] and Ebrahimi et al [149].…”

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.

“…As shown in ODFs (Figure ), Dillamore and Copper components remain the major components after the 7th and 9th ARB passes. It was reported that the Dillamore and Copper components originated from the shear component . The shear deformation component (usually Rotated Cube {001} <110>) is created on the surface of the rolled sheet due to the difference of linear velocity between the roller and sheet and also the friction at the interface of sheet and rollers .…”

Microstructure and Texture Development in Al–3%Brass Composite Produced through ARB

et al. 2017

View full text Add to dashboard Cite

In the present work, aluminum-3% brass composite sheets are produced by accumulative roll bonding (ARB) process up to nine passes at ambient temperature. Evolution of rolling texture is studied by texture measurement using X-ray diffraction method. The results show that ARB process leads to the formation of copper ({112} <111>) and Dillamore ({4 4 11} <11 11 8>) as the major texture components. The intensity of copper and Dillamore components enhances to values as high as 19 times that of random with increasing number of passes to 9. It is observed that the 5th pass is a transition in development of the texture components, after which the intensities undergo a drop. The textures are comparable to ARB process of high purity aluminum, indicating that the addition of 3% brass particles do not cause any significant change in the deformation behavior. Electron backscatter diffraction (EBSD) technique is used to examine the microstructure; the results reveal formation of ultrafine grains (UFG), starting in the 3rd pass and covers the entire structure after the 5th pass. The major mechanisms involved are identified as rotation of the sub-grains, as well as grain boundary migration.
