In the dissertation it has been shown, that so called “time-thermal treatment” (TTT) of the alloy in liquid state as overheating the metal with around 250°C above T_liq. and detailing it in temperature for 30 to 40 minutes has the influence on changing the crystallization parameters (T_liq., T_Emin., T_Emax., T_E(Me), T_Sol.). It was ascertained, that overheating the AlSi17Cu5Mg alloy substantially above T_liq. results with microcrystalline structure. Evenly distributed in the eutectic warp primeval silicon crystals and supersaturated with alloying additives of base content (Cu, Mg, Fe) of α(Al) solution, ensures not only increase durability in ambient temperature, but also at elevated temperature (250°C), what due to it’s use in car industry is an advantage.
