Removal of iron from secondary aluminum alloys by metal melt filtration (A07)

• Subject Area: Thermodynamics and Kinetics as well as Properties of Phases and Microstructure of Materials
• Term: from 2016 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 169148856

The usability of functional filter materials, produced within the SFB920, for removal of primary solidified, Fe-containing intermetallic in order to reduce the Fe-content in secondary Al-melts is investigated within the subproject A07. Therefore, the Al-Si-Mg alloy A356 used within the CRC 920 with typical Fe-contents will be conditioned under the influence of Mn and Cr close above the liquidus-temperature of the (Al)-solid solution. The interaction of the secondary Al-alloys with the functional filter materials will be particularly studied regarding nucleation of Fe-containing intermetallic and the potential formation of in-situ layers to bind Fe.
