- Аннотация: The methods for the preparation of quasicrystalline intermetallic compounds in the protective matrix in the systems Al65Cu22Fe13 and Al54Cu9Mg37 were developed. They are formed both earlier and from elements during the formation of a metallopolymer composite material. Three methods of preparation are optimal: from low-dimensional powders of quasicrystals and film-forming polymers, by the in situ formation of quasicrystals during the thermal decomposition of the corresponding precursors, and via the thermal polymerization of metal-containing monomers (components of quasicrystals) followed by the controlled pyrolysis of the metallopolymers that formed. The metallopolymer composite obtained by the incorporation of Al63Cu22Fe13 into the high-density polyethylene or polyacrylamide matrix affords up to 10 wt.% cubic phase of beta-Al-50(Cu,Fe)(50). The products of thermal decomposition of the low-molecular-weight precursors are a mixture of the quasicrystalline (Al65Cu22Fe13) and crystalline (cubic beta-Al-50(Cu,Fe)(50) and tetragonal omega-Al7Cu2Fe, Al2Cu) phases. The thermolysis of the metallo-polymer composition yields a finely dispersed powder, whose main component is an alloy Al7Cu3Mg6 with an admixture of the Al2CuMg phase.
