Strong and ductile recycled Al-7Si-3Cu-1Fe alloy: Controlling the morphology of quasicrystal approximant α-phase by Mn and V addition

Effects of Mn addittion, cooling rate and holding temperature on the modification and purification of iron-rich compounds in AlSi10MnMg(Fe) alloy

“…Metallurgy of Fe-rich intermetallic phases become more complex as the number of elements in the alloy are increased. Depending on the secondary element contents, such as Mn, Cr, etc., crystallography, and morphology of Fe-rich intermetallic phases can be modified [ 18 , 23 , [28] , [29] , [30] , [31] , [32] , [33] , [34] ]. Some authors studied the effects of the addition of different elements to modify the platelet-like morphology β-Fe phase to the less detrimental α-Fe phase [ 18 , 31 , 35 , 36 ].…”

“…Consequently, it can be applied in the recycling of materials by estimating the total amount of corrector elements required during casting. CALPHAD-based software was successfully employed to avoid the formation of undesirable Fe-rich compounds by elemental modification in Al–7Si–3Cu cast alloy [ 29 ], and in Al–Mg–Mn–Fe alloys processed by squeeze casting without heat treatment [ 18 ]. The mechanical properties of Al–Mg–Si–Fe alloys also were improved by the proper addition of Mn calculated by CALPHAD [ 12 ].…”
