“…By using composites, such as an Al/Cu plate with 80% Al, the weight of building plates is reduced by half compared with those of conventional Cu plates [2]. On the other hand, composites, such as the Al/steel used for an automotive trim, possess good combination of properties; the steel provides strength and good appearance, whereas the aluminum can be easily fabricated and can protect the auto body from galvanic corrosion [2,92]. Mechanical behaviors and formability of multilayer composite materials have been studied, and mechanisms responsible for many of their unique properties have been proposed [89,[99][100][101].…”

Layered composite materials have become an increasingly interesting topic in industrial development. Cold roll bonding (CRB), as a solid phase method of bonding same or different metals by rolling at room temperature, has been widely used in manufacturing large layered composite sheets and foils. In this paper, we provide a brief overview of a technology using layered composite materials produced by CRB and discuss the suitability of this technology in the fabrication of layered composite materials. The effects of process parameters on bonding, mainly including process and surface preparation conditions, have been analyzed. Bonding between two sheets can be realized when deformation reduction reaches a threshold value. However, it is essential to remove surface contamination layers to produce a satisfactory bond in CRB. It has been suggested that the degreasing and then scratch brushing of surfaces create a strong bonding between the layers. Bonding mechanisms, in which the film theory is expressed as the major mechanism in CRB, as well as bonding theoretical models, have also been reviewed. It has also been showed that it is easy for fcc structure metals to bond compared with bcc and hcp structure metals. In addition, hardness on bonding same metals plays an important part in CRB. Applications of composites produced by CRB in industrial fields are briefly reviewed and possible developments of CRB in the future are also described.

In this study we dealt with the characterisation of an aluminium‐clad steel material compound and the influence of the manufacturing process on its fatigue behaviour. As components of the Al6016‐T4/FeP06 material compound are manufactured predominantly by rolling and deep drawing, the influence of the plastic deformation during manufacturing on the fatigue behaviour must be investigated. Particularly, the cyclic hardening behaviour of FeP06 has a marked effect on the fatigue life of the aluminium–steel compound. Simulation models for fatigue life estimation of this material compound must therefore consider the influence of the plastic deformation which occurs, e.g. during deep drawing, on the fatigue behaviour. This study focused on the technological influences of the rolling process on the fatigue behaviour of an AA6016‐T4/FeP06 compound. The influence of the load sequence on the S/N‐curve of FeP06 was also studied.

“…Pan and Hosbons [13] provided a comprehensive description on the determination of the concentration of solute carbon and nitrogen in ferrite, and the evaluation method of strain aging susceptibility in low carbon steels. De and De Cooman et al [15][16][17] studied the effect of prestraining on bake hardening in ULC steel and the effect of Al coating, and found the AlN diffusion barrier at the coating-substrate interface, and the coating Al can act as a trap for free nitrogen and reduce the strain aging susceptibility. The Angang Group and the Boagang Group, in China, have produced various bake hardening steels, and the National Standard of China GB-T24174-2009 was issued to define the determination method of the BH value.…”

In the present work, specimens prepared from coarse grained low carbon steel with different prestrains were baked and then, their bake hardening (BH) property and internal friction were determined. TeM was used to characterize the dislocation structure in BH treated samples. The measurements of internal friction in prestrained samples and baked samples were carried out using a multifunctional internal friction apparatus. The results indicate that, in coarse grained low carbon steel, the bake hardening properties (BH values) were negative, which were increased by increasing the prestrain from 2 to 5%, and then were decreased by increasing the prestrain from 5 to 10%. In the specimen with prestrain 5%, the BH value reached the maximum value and the height of Snoek-Köster peak was observed to be the maximum alike. With increasing the prestrain, both of the BH value and Snoek-Köster peak heights are similarly varied. It is concluded that Snoek-Köster and dislocation-enhanced Snoek peaks, caused by the interactions between interstitial solute carbon atoms and dislocations, can be used in further development of the bake hardening steels.
