“…Detailed results on the Al2N/Al2N sheets shown here can be found in ref. [126], while the Al2N/Al5N laminates have been the topic in publications and . A report about Al5N/Al5N ARB sheets of high‐purity aluminum is still in preparation, but some preliminary results will be presented here as well.…”

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,...

“…As ARB can well control the final thickness of multiple layers, numerous LS materials have been produced by this technique. [104][105][106][107][108][109][110][111][112][113][114][115][116][117] Decreasing the interface spacing in LS materials is related to the improvement of strength and ductility during uniaxial tension. 104) However, overlapping HBAR from neighboring interfaces may affect the GND pileup formation.…”

Heterostructured materials (HSMs) constitute heterogeneously distributed soft and hard zones with a mismatch in mechanical or physical properties of at least 100% between them. A synergistic effect resulting from the interactive coupling between the heterogeneous zones surpasses the properties predicted by the rule of mixtures. Therefore, the mechanical or physical properties of HSMs are not achievable by their homogeneous counterparts. HSM production commonly requires plastic deformation to refine the microstructure and subsequent partial recrystallization heat-treatments to obtain heterogeneous distributions of grain size, texture, or defect density. Other routes are by applying surface plastic deformation or by stacking layers with a high property mismatch between them. All of those routes can be achieved by severe plastic deformation (SPD) techniques. This overview focuses on describing the fundamentals of HSMs produced by SPD. A critical description of the physics of SPD and HSMs, as well as the factors influencing their microstructural evolution, perspectives, and outstanding issues, are included. A critical comparison of the strength-ductility relationship in HSMs produced by different SPD techniques is also included to guide upcoming research. This overview is intended to serve as a basis for understanding and designing future HSMs produced by SPD.
