Solubility of Fe in Al Rich Region of Al–Mg–Si System at 973 K

Solubility of Fe in the liquid of Al–Mg–Si alloys was determined at 973 K. The liquid of Al–Mg–Si alloy with Fe concentration of up to 15 wt% was heated at 973 K. After equilibration a part of liquid was sampled and solidified to analyze the chemical compositions by X-ray fluorescence. The solubilit...

Zusammenfassung:Solubility of Fe in the liquid of Al–Mg–Si alloys was determined at 973 K. The liquid of Al–Mg–Si alloy with Fe concentration of up to 15 wt% was heated at 973 K. After equilibration a part of liquid was sampled and solidified to analyze the chemical compositions by X-ray fluorescence. The solubility of Fe was determined as functions of Mg and Si concentrations in weight percent as follows, CFe = –(0.14 ± 0.00)CMg + (0.02 ± 0.01)CSi + (2.74 ± 0.03) The solid phase coexisting with the Fe saturated liquid was FeAl3 in which Si was dissolved up to 2.4 at%.
