METHOD OF PRODUCTION OF POWDER OF QUASI-CRYSTALLINE SINGLE PHASE ALLOY Al-Cu-Fe

摘要

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 530-540C in vacuum chamber in atmosphere of inert gas or in forevacuum in pressure range 1-510-2 Top. ^ EFFECT: simplification of method, and acceleration of synthesis. ^ 3 cl, 3 dwg, 3 ex
