The paper presents the results of studies on the effect of the AlSi17Cu5 alloy overheating to a temperature of 920°C and modification with phosphorus (CuP10) on the resulting mechanical (HB, Rm, R0.2) and plastic (A5 and Z) properties. It has been shown that, so-called, "time-thermal treatment" (TTT) of an alloy in the liquid state, consisting in overheating the metal to about 250°C above Tliq., holding at this temperature by 30 minutes improves the mechanical properties. It has also been found that overheating of alloy above Tliq. enhances the process of modification, resulting in the formation of fine-grain structure. The primary silicon crystals uniformly distributed in the eutectic and characteristics of the \alfa(Al) solution supersaturated with alloying elements present in the starting alloy composition (Cu, Fe) provide not only an increase of strength at ambient temperature but also at elevated temperature (250°C).
