Quasicrystalline phase formation by heating a mechanically alloyed Al65Cu23Fe12 powder mixture

Abstract:

Elemental powder mixtures of a Al65Cu23Fe12composition milled for two and four hours in a planetary ball mill were used to form quasicrystals. Annealing of the as-milled samples led to complex solid-state transformations. During the heat-up a sequence of solid-state reactions takes place in the as-milled powder. These reactions were studied both by differential scanning calorimetry and X-ray diffraction methods. An analysis of the phase formation shows the effect of the difference in the ther...
