| Abstract Scope |
We propose roll-bonded steel scrap laminates as an energy-efficient material alternative for structural applications while avoiding CO2 intensive scrap recycling route. Previous investigations on roll-bonding typically aim at demonstrating a step-change increase in performance compared to monolithic alloys by bonding steels at ideal conditions. Therefore, metal configurations with severe surface limitations (e.g., oxidation, damage, roughness) are almost always avoided. Instead, in this work, we turn our attention to the formability response of the laminated steels in the presence of imperfect initial conditions. Despite the inevitable deficiencies in bond strength, mechanical characterization of the laminates subjected to different strain paths showed that their formability is sufficient for a wide range of forming operations. Our microstructural and mechanical analyses demonstrated that this intriguing performance is due to the favorable stress states acting on the interface, not promoting delamination. |
