| Abstract Scope |
Aluminum alloys are relatively easy to recycle because of their low melting point compared to other metallic materials. More importantly, aluminum remelting is much less energy-intensive and CO2-emitting than its primary extraction. Sorting is the best practice to avoid contamination. Unfortunately, this strategy is not perfect and lead to the presence of paints, organics, and other metals. The latter introduces tramp elements which affect the phase assemblage of aluminum alloys as well as their physical/mechanical properties.
Traditionally, cast alloys were targeted as recycling vectors because of their tolerance to impurities. The higher demand for wrought alloys makes these materials ideal candidates to increase recycling activities. This work reports a series of experiments on the controlled contamination of wrought alloys with tramp elements such as Fe and V. The energetics of several solid solutions formed in these alloys are explored with the use of atomistic simulations and computational thermodynamics. |
