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,...

“…The stainless steel clad plate was fabricated by cladding a stainless steel on the surface of the high strength low alloy (HSLA) steel. 1) Recently, explosive cladding, 2,3) rolling cladding 4,5) and weld overlay cladding [6][7][8][9] have been used to produce the clad plates. Explosive cladding is a widely applied technique to produce the clad plates, especially for the metals with dissimilar melting points.…”

304 austenite stainless steel plate and HSLA steel plate were subjected to vacuum rolling cladding (VRC). The microstructure characteristic and properties of the clad interface were investigated in detail. During the VRC process, the clad interface was held at a high vacuum all the time, resulting in significantly decreased oxidation at the interface. A small amount of very fine oxide particles (diameter < 0:5 mm) can be found at the clad interface, and no obvious defects were observed. The remarkable diffusion of Ni and Cr elements led to the formation of a transition zone with high hardness. The shear strength of the clad interface was as high as 487 MPa, and the fracture occurred at the HSLA steel near the transition zone. No cracks were found at the clad interface after the 180 bending tests with both outside and inside manners.

“…However, if the annealing time and/or temperature exceed a certain value, the development of interfacial structure leads to the formation of weak layers in the interfacial region and damage the bonds. [5][6][7][8] Al/Cu joint rapidly loses its mechanical integrity when the total width of intermetallic phases exceeds 1 um. However, some questions require further studies and the interfacial structure for misfit materials needs to be investigated in depth.…”

Effect of Annealing on the Interfacial Structure of Aluminum-Copper Joints

The aim of this study is to investigate the structure development and growth kinetics of the interfacial structure of cold roll bonded Al/Cu bimetal sheet. An interfacial structure is developed during the annealing process. The characteristics of the constituent phases at the interface of Al/Cu bimetal are studied by means of scanning electron microscope (SEM), X-ray diffraction (XRD) and transmission electron microscope (TEM). The results indicate that an obvious multi-layers interdiffusion structure is developed at the Al/Cu interface. The diffusion layer is consisted of four intermetallic compounds; Al 2 Cu, AlCu, Al 3 Cu 4 and Al 4 Cu 9 . The growth of these intermetallics during annealing can be achieved by the diffusion process. The activation energies of Al 2 Cu, AlCu + Al 3 Cu 4 , Al 4 Cu 9 and the total intermetallic layer are found to be 97.504, 107.46, 117.52 and 107.85 kJ/mol, respectively. These intermetallics generally possess higher hardness values than those of the corresponding base metals. AlCu and Al 3 Cu 4 exhibit much higher hardness than that of Al 2 Cu and Al 4 Cu 9 , which implies lower fracture toughness. The observation of crack propagation paths shows that fracture mainly occurs in the intermetallic compound layers of AlCu and Al 3 Cu 4 , which are located between Al 2 Cu and Al 4 Cu 9 .
