摘要：

The phase transformations in Al-Cu-Fe cast alloys in the region of existence of the ico-phase are characterized via X-ray diffraction, X-ray fluorescence, and scanning electron microscopy. It is established that the production of multiphase structures consists of a mixture of quasi-crystalline and approximant phases, the amount and morphology of which depend on both the shield composition and crystallization mode. The optimum annealing time for the cast samples at 800°C has been determined, resulting in complete transformation of approximant crystalline phases into a quasi-crystalline ico-phase. © 2015, Allerton Press, Inc.
