The rapidly solidified (Al75Cu17Mg8)100-xZnx( x=0,1,2,3 at. %) alloys were obtained by melting in an induction furnace and then rapidly quenched by the planar flow casting (PFC) method in instalations, created at the IMSTCA-BAS. By TEM and X-ray analises were obtained data, that the microstructure of the alloys is an amorphous matrix with nanosized particles with dimensions 16÷.90 nm. The obtained amorphous alloys have relatively good glass forming ability. With increasing content of Zn the amount of the amorphous phase and glass transition temperature Tg also increase
