| Abstract Scope |
One of the many ways materials science is adapting modern materials to combat the climate crisis is to focus on repurposing scrap streams into value streams, which increases material availability while decreasing emissions. Aluminum is highly recyclable and versatile, though not all aluminum scrap streams are readily convertible into value streams; these streams accumulate elements such as Si and Fe which reduce the recyclability into conventional aluminum alloys. Opportunities to create new aluminum wire feedstocks for welding and additive manufacturing exist, though the accumulation of other elements contributes to secondary phase formation. In this presentation, we will discuss the progress we have made towards designing recycled aluminum feedstocks from the most contaminated material and producing deposits using gas tungsten arc welding. We discuss the resulting solidification cracking susceptibility, embrittling intermetallic compound and secondary phase formation, and heat treatment response. |
