The Influence of Alloy Composition and Liquid Phase on Foaming of Al−Si−Mg Alloys [PDF]

open access: yes, 2020
The foaming behaviour of aluminium alloys processed by the powder compaction technique depends crucially on the exact alloy composition. The AlSi8Mg4 alloy has been in use for a decade now, and it has been claimed that this composition lies in an “island
