Structural steel-aluminum sandwich composites based on low-carbon steel 006/IF

This contribution draws practical implications of a recently published estimation of the tensile ductility in laminated composites made of two ductile materials, typically metals or alloys, which harden as both the strain and the strain-rate increase. To this end, the literature is surveyed to collect values for the strain hardening exponent, the strain-rate sensitivity and the strength constant for a wide range of engineering metals and alloys. Material combinations that might produce ductile laminated metal composites are then examined in light of the data and theory. A simple graph is proposed, which gives a direct reading of the predicted elongation to failure of composites containing equal volume fractions of any two materials among those surveyed. The resulting plots show material combinations in which a more ductile material can significantly increase, within a Laminated Metal Composite (LMC), the tensile elongation of a less ductile material. In this role, 304 stainless steel and commercial purity iron emerge as sensible possibilities.

“…This allows saving expensive materials, improving the reliability of constructions and equipment. As an example, steel-aluminum [1][2][3][4][5], magnesium-aluminum [6][7][8], copperaluminum [9][10][11] clad composites, as well as steel-based composites [12], are being actively developed and introduced into the manufacturing of vehicles. The use of parts made of composites in car construction allows one to reduce their weight, improve their performance characteristics, and reduce carbon emissions into the environment.…”

“…In addition, by adding an intermediate transition layer or coating, the formation of brittle and hard intermetallic compounds can be avoided, effectively promoting the creation of a bond between the metals. Thus, the bond strength is improved [26,27]. Huang [21] used plasma coating technology to closely combine a coating layer with the surface of a steel plate, and then they hot rolled this with an aluminum plate to prepare a thick steel/aluminum composite plate with a total thickness of 13.5 mm.…”

Given the characteristics of a thick steel/aluminum composite plate, such as its large thickness and the significant differences between its components, it is difficult to prepare using direct rolling. Instead, a thick steel/coating/aluminum composite plate may be successfully prepared by combining supersonic flame coating technology with a hot rolling composite process. In this study, the interface shear strength test, SEM, EDS, and other detection methods were applied to investigate the effects of the reduction rate and coating thickness on the interface structure and mechanical properties. The results show that under the condition of single-pass direct rolling, the micro-interface of steel/aluminum is improved with an increase in the reduction rate, but the bonding strength of the interface remains poor. After adding the coating, the thickness of the diffusion layer and the shear strength increase significantly. When the coating thickness is reduced to 0.1 mm, the deformation coordination and shear strength of the composite plate are further enhanced under the combined action of mechanical interlocking and metallurgical bonding. The tensile shear fracture is mainly located at the steel/coating interface. The interfacial shear strength reaches 66 MPa, which exceeds the requirements of the US military standard MIL-J-24445A (SH) for steel/aluminum shear strength. The research results thus support the use of this new method for the simple and efficient production of thick steel/aluminum composite plates.
