Alloys of Sc and Al with or without magnesium are considered promising materials of future. The reinforcement effect of scandium on the properties of aluminum was the primary reason for this study. In addition to improvements on the mechanical strength, resistance to recrystallization, resistance to intergranular fracture and corrosion and thermal stability of aluminum alloys were greatly affected by the presence of small concentrations of scandium. The main source of scandium is the Sc2O3 by-product obtained during uranium,tungsten or tantalum production. It has been deemed possible to produce Sc by the molten salt electrolysis method by dissolution of Sc2O3 in Na3ScF6 as in the Hall-Héroult process. Al-Sc alloy formation by the reduction of other Sc bearing compounds in a molten salt containing CaCl2 was observed in this study. According to XRD, SEM-EDS and optical microscopy analyses,it was seen that Al3Sc intermetallic was successfully formed and distributed homogeneously throughout Al matrix
