Stability of quasicrystalline phases in AlFeV alloys

Abstract

Quasicrystalline phases have been produced in a series of ternary AlFeV and binary AlV alloys prepared by melt spinning techniques. Differential scanning calorimetry and transmission electron microscopy have been employed to characterize the thermal stability and microstructure of these phases. The stability of these phases is largely dependent on the alloy composition. The results suggest that the lattice parameter of the icosahedral phase obtained in the ternary alloys is dependent on the Fe:V ratio in the alloys.
