“…Additionally, the thickness of the diffusion layer and, correspondingly, the bonding strength can be altered by means of subsequent heat treatment. The growth of intermetallic phases of Fe–Al system can be initiated during annealing at temperatures above 350 °C . At the same time, the range of sensitization temperatures for austenitic stainless steel lies above 500 °C.…”

The manufacturing of clad strips by means of twin-roll casting is a prospective trend regarding the production of lightweight materials. This study is dedicated to an analysis of bond formation conditions during the twin-roll casting of clad strips of aluminum EN AW-1070 and an austenitic stainless steel 1.4301. The procedures of steel substrate preparation and their influence on the diffusion bond are investigated. These include surface pretreatment of the steel substrate by means of mechanical grinding and laser irradiation as well as its pre-heating. Using the different sets of process parameters, the clad strips with a thickness of 2.5 mm are manufactured and characterized. Light and electron microscopy are used to characterize the microstructure of the aluminum layer and the bond zone and to investigate the mechanism of bond formation. The evaluation of the strips' properties is carried out by means of adhesive tensile tests, peeling tests, uniaxial tensile tests, and fatigue tests. The influence of each of the substrate preparation methods as well as post heat treatment on the parameters of bond zone and the mechanical properties of the clad strip is investigated. The implementation of the investigated manufacturing method allows producing thin clad strips with excellent characteristics.

“…Considering R i1 equals to punch radius R p at the punch-sheet contact zone, maximum bending moment M p can be calculated by integrating the circumferential stress in each layer using equation (8). Therefore, during air bending, considering linear moment distribution along sheet length, equation (17) can be presented…”

“…In this article, cold roll bonding (CRB) of Al/Cu clad sheets has been performed considering all reported studies. [3][4][5][6][7][8] Springback violates the product's shape precision; therefore, it should be compensated. Since studying springback, whether to avoid or compensate it, is appealing, many studies focused on springback behavior in bending processes.…”

In this article, an advanced analytical formulation is developed to predict thickness change of an aluminum/copper clad sheet. Springback analytical formulation is also introduced using the combination of advanced and primary bending theories in air bending process. Experiments were performed to verify analytical results and to investigate the effect of different geometrical parameters such as punch stroke, die opening, punch radius and setting condition on the springback. It was observed that die opening had the most striking effect, while setting condition had a negligible effect on springback. On the other hand, setting condition played a crucial role on thickness change in bent clad sheets. Clad sheet thickened in the Al/Cu setting condition, while in the Cu/Al setting it thinned. Finite element method simulation was also applied to verify analytical predictions of the thickness change and study stress distribution in the layers of the clad sheet. Good correlation was observed between analytical and numerical results.

“…Majority of literature about roll bonding of metals is focused on the production of laminated non-ferrous materials such as aluminum [13][14][15][16][17][18] and copper [17] or laminated non-ferrous and ferrous composites, e.g., steel and aluminum [19][20][21][22][23][24][25][26][27][28][29][30][31]. Only few papers are concerned with steel laminated composites.…”

In order to investigate the roll bonding of high-alloy transformation induced plasticity (TRIP) and twinning induced plasticity (TWIP) steel, roll-bonded sheets of the TRIP and TWIP steel were manufactured starting from hot rolling, followed by brushing and cold rolling. Both, the microstructure and mechanical properties of the roll-bonded sheets were characterized by metallographic investigations, and tensile and T-peel tests. Preliminary results, such as an occurrence of an adhesive bonding between two TWIP steel sheets and between TRIP and TWIP steel sheet after a thickness reduction of approximately 50% were obtained. Moreover, the formation of deformation-induced martensite leads to outstanding mechanical properties of the roll-bonded composite sheet. An ultra-fine grained microstructure was observed in the bonding zone after only one roll-bonding process. The obtained promising results demonstrate the possibility of the development of an accumulative roll-bonding process for TRIP/TWIP steel composites.
