FIELD: metallurgy.
SUBSTANCE: invention relates to methods of metal materials with quasi-crystalline structure powders receiving. Method includes receiving of initial mixture of powders with required content, mixing of initial powder mixture, its heating and isolation in oxygen-free atmosphere and following cake reduction till receiving of powder with required size. Mixing is implemented by means of mechanical activation of powders mixture in high-energy unit. Heating and isolation is implemented by stepped mode. At the first stage - at the temperature and time enough for formation of precursor transient phase, and at the second - at the temperature and time enough for transformation of precursor transient phase into quasi-crystalline structure.
EFFECT: providing of efficient production of method and high quality of received quasi-crystalline material.
