Abstract Scope |
Aluminum-steel clad composite is a material of great potential for various industrial applications due to a combination of a low density of Al and a high strength of steel. A high corrosion resistance and a low cost of both monomaterials makes the clad strip even more attractive. A suitable option of a flat composite preparation is twin-roll casting, which is supposed to be an energy and material saving method. Additionally, a subsequent heat treatment could be applied to enhance the diffusion joint. However, using high-temperatures procedures is limited by a formation of a brittle intermetallic layer in the interfacial region between steel and aluminum, which essentially influences the final mechanical properties of the composite. In the study, effect of subsequent annealing was investigated. Experimental methods including electron microscopy and resistometrical measurements were complemented by finite element method calculations for further interpretation of the measured data. |
