Preparation and analysis of quasicrystalline phases by high energy ball milling and x-rady diffraction

摘要

The cosequences of solid-state reactions in mechanically alloyed Al-Cu-Fe powders were studied using advanced techniques of X-ray diffraction pattern interpretation. A set of intermetallic phases was identified which appeared as a result of mechanical alloying and subsequent annealing. These intermetallics were the intermediate products formed during to gradual mechanical and thermal homogenisation and excitation.
