| Abstract Scope |
The future of materials science is being driven by the adaptation of modern materials to combat the climate crisis while ensuring material availability and stability, focusing on repurposing scrap streams into value streams. Aluminum is rising in popularity across multiple industries due to its versatility and recyclability, though not all scrap streams are readily convertible into value streams. Aluminum scrap streams accumulate elements such as Si and Fe that reduce the recyclability into conventional aluminum alloys. However, opportunities exist to create new aluminum wire feedstocks for additive manufacturing that are derived from the aluminum scrap stream. In this presentation, we will discuss our progress towards designing recycled aluminum wire feedstocks by considering solidification cracking susceptibility, embrittling intermetallic compound formation, and heat treating response. We demonstrate that with careful composition modification, gas metal arc welding and wire arc directed energy deposition can be used to increase the recyclability of aluminum. |
