| Abstract Scope |
Traditional steel manufacturing/recycling accounts for a tremendous amount of global CO2 production and energy consumption yearly. This prompts further research into new techniques for solid state recycling, many of which depend on diffusion bonding to create a mechanical bond at elevated temperatures between constituent pieces without melting the metal. Our study shows that diffusion bonding can be accomplished through high strain rate process including roll-bonding and forge-welding, which can be modified with chemical processing such as fluxing. These techniques result in bond interfaces that are imperfect, yet preform similarly in forming operations to its monolithic counterparts, meaning that steel stock can be produced directly from scrap locally and used immediately. These techniques, combined with chemical processing, expand the range of materials that can be bonded in solid state, allowing for direct recycling of materials that are otherwise melted down and recast, including stainless steel and corroded mild steel. |
