Abstract Scope |
In this work, we aim to formulate an AlSi10Mg alloy from aluminium recovered from IBA (IBA-Al) towards potential applications such as Additive Manufacturing and High Pressure Die Casting. To this end we use arc melting as a fast material screening method and controlled melting technique for alloy formulation. We first investigate the effect of arc melting of (un-alloyed) IBA-Al on resulting microstructure and chemical composition using EDS analyses. IBA-Al typically contains oxides which must be handled, as these may promote nucleation of defects such as cracks. We explore the potential of arc melting for partial oxide removal from IBA-Al and compare with IBA-Al treated with salt to remove oxides. Finally, we show initial microstructure analysis of formulated AlSi10Mg from IBA-Al, and the impact of using salt-treated IBA-Al vs. non-salt-treated IBA-Al. This work demonstrates the initial potential as well as challenges with alloy formulation of from IBA-Al. |
