Abstract
Quasi-crystalline Al65Cu23Fe12 powders have been obtained by the method of plasma-chemical synthesis. Coarse particles have a spherical form and an inhomogeneous structure because of the laminar growth of crystallites toward the surface of the particles. The influence of heat treatment on phase formation and structuring in Al–Cu–Fe alloys has been studied. It has been found that the heat treatment of as-prepared powders changes the phase relationship in the quasi-crystalline alloy.
