FIELD: metallurgy.
SUBSTANCE: method consists in mixing source mixture of powders of aluminium, copper and iron in air at ratio of components corresponding to domain of existence of quasi-crystalline phase of Al-Cu-Fe system alloy and in heating it in oxygen-free atmosphere. Dry components of mixture are mixed. Heating is carried out to temperature of beginning of self-propagating high-temperature synthesis. Further obtained product is crumbled to powder of required size. Also mixture is heated to temperature 530-540°C in vacuum chamber in atmosphere of inert gas or in forevacuum in pressure range 1-5·10-2 Top.
EFFECT: simplification of method, and acceleration of synthesis.
