Cold roll bonding of multi-layered bi-metal laminate composites

Interface-correlated deformation behavior of a stainless steel-Al–Mg 3-ply composite

“…As a type of solid-state welding/joining process for joining similar and/or dissimilar metals, roll-bonding technology is considered to be the most common route to manufacturing multilayered metallic composites because it allows for the cost-effective continuous production of multilayered clad metals [5][6][7]. In order to improve the bonding properties at the interface, post-roll-bonding treatment such as annealing or additional rolling is sometimes given for some constituent parts of the multilayer composites [8].…”

Energy absorption mechanism of Al–steel bilayer sheets produced by cold roll welding during wedge tearing

“…Since in this research the effect of cold weld is investigated on the energy absorption of bilayer sheet through tearing test, some of the specimens must be non-welded. It has been shown that interfacial coefficient of friction causes difference in thickness fraction of layers in bilayer sheet [16]. Although this effect is negligible but for assuring that this term is identical for investigating the tearing energy absorption of welded and non-welded sheets, the interfacial surfaces of sheets that should not be welded were brushed, but to avoid bonding, the interfacial surfaces were printed by gypsum micro-size powder.…”

Mechanical properties of laminated steel-based composite materials fabricated by hot rolling

“…These post-rolling ratios were found by microstructure examination under an optical microscope. A detailed analysis of thickness evolution vs. rolling parameters, as reported in 11 , was impossible, due to multiple passes having been carried out. Despite that, it was confirmed that the "soft" constituent, AISI 304L steel, undergoes larger reductions than the 55C15N steel.…”

“…These included, for instance, titanium alloy/steel, 2-3 aluminum alloy/aluminum alloy, 4 aluminum alloy/steel, 5 brass/steel, 6 steel/steel [7][8][9] and other possible combinations. 10 Laminated metallic composites offer an abundance of topics for study, ranging from fabrication, where the flow of layers during deformation can be explored, [11][12][13] through their overall mechanical properties 14 measured, for instance, by conventional tension testing 10,15 or by three-point bend test; 16,17 used for mapping delamination during failure. 18 One can also investigate internal stresses on the interlayer interface, for instance, in a composite fabricated of martensitic and austenitic steels.…”
