FIELD: metallurgy.
SUBSTANCE: metal powders are mixed at a ratio corresponding to quasi-crystalline phase field for Al-Cu-Fe system. Charge is melted in crucible simultaneously with dispersion by an electric arc pulse discharge in a vacuum chamber in inert gas medium, where anode is the vacuum chamber surface and conductive equipment inside it while cathode is the melting cricuble. Electric arc pulse frequency is 0.5 kHz, pulse duration is 10 to 300 mks. Quasi-crystalline alloy powder is condensed by heat exchange on the cooling surface of the vacuum chamber.
EFFECT: improved quality of spherical powder of quasi-crystalline alloy, including higher homogeneity and reduced dispersion range.
