Features of formation quasicrystalline
phase in cast alloys of the system Al–Cu–Fe
Abstract
By X-ray, X-ray fluorescence and scanning
electron microscopy the phase transformations in cast alloys of Al–Cu–Fe in
existence ico-phase. It was established that the production of
multi-phase structures consisting of a mixture of the quasicrystalline phases
and approximant, amount and morphology which depends on the composition shields
and crystallization mode. The optimal annealing cast samples at 800° C, which
resulted in approximant crystalline phases are completely transformed into a
quasicrystalline ico-phase.
Key words: alloys Al–Cu–Fe, quasicrystallic
ico-phase, physicochemical analysis, isothermal annealing.
