In this study, the metastable phases that can be formed in Al80Fe10Ti5Ni5 alloy by melt spinning and mechanical alloying techniques have been investigated. The produced samples were examined by X-ray diffraction, transmission electron microscopy, and differential scanning calorimetry. The results showed that the phases in Al80Fe10Ti5Ni5 alloy during rapid solidification are Al13(Fe,Ni)4, Al3Ti and amorphous phases. The formation of equilibrium phases was completely suppressed by mechanical alloying. It is of note that supersaturated solid solution, decagonal, and amorphous phases are three separated phases that can be formed during mechanical alloying of an Al–10%Fe–5%Ni–5%Ti powder mixture.
