Mechanism of Fe removal by Sn addition in Al-7Si-1Fe alloy

Another method is flux refining, which removes Fe from Al alloys by adding Fe-rich intermetallics that form elements. Boron is the most studied element in flux refining method [41], and there are two main ways to add B: Na 2 B 4 O 7 and Al-B master alloy. The mechanism is that the Fe 2 B phases are formed by the reaction between Fe and the B-containing …
