Aluminium-based quasicrystals have properties of great interest for many applications, e.g. hard coatings, but are rather difficult to produce in large quantities, as they are stable only within a narrow composition domain[2, 3].
Alloy powder with nominal composition Al67Cu23Fe10 was prepared by ball-milling of elemental metallic powders. The as-milled powder consists mainly of a nanocrystalline Al(Cu,Fe) solid solution.
The structural phase transitions upon heating under different pressures were investigated by in-situ X-ray diffraction at the F2.1 beamline of DESY-HASYLAB (Hamburg, Germany), in order to establish a PRESSURE-TEMPERATURE phase diagram. A single-phase quasicrystalline powder was obtained after a sequence of phase transitions taking place at temperatures between 250-300C and 700-800C, with phase transition temperatures varying with pressure. The quasicrystalline phase was shown to be stable after quenching under pressure.
