Melt-spun ribbons of Al91Mn6Fe2X1 (X=Mn, Mo, V) were used as a feedstock to obtain bulk materials by mechanical milling and subsequent hot-pressing compaction. Modifications of the chemical composition of the Al-Fe-Mn base ternary alloy with the transition metals Mo and V facilitated hot-compaction based preparation of bulk samples with microstructures that retained significant fractions of the quasicrystalline I-phase. The transition metal modified bulk alloy samples exhibited enhanced values of compressive strength and high hardness.
