dc.description.abstractThe hypoeutectic aluminum alloy AlSi5Cu2Mg is used in the field of high-strength cylinder head castings for the automotive sector due to its favorable combination of mechanical, physical, and foundry properties. The regulation of the chemical composition of the AlSi5Cu2Mg alloy set by the manufacturer limits the use of standard grain refiners based on Al-Ti and Al-Ti-B due to the limited content of Ti (max. 0.03 wt.%). The article is focused on the possibility of increasing the Ti content in this specific alloy above 0.03 wt. % Ti. The article investigates the effect of graded addition of Ti (0.1; 0.2 and 0.3 wt. % Ti) on the resulting mechanical and physical properties of the AlSi5Cu2Mg alloy. In this paper, the effect of T6 heat treatment on the resulting mechanical and physical properties was also evaluated. The physical properties of the experimental alloys with Ti addition decreased with increasing Ti content. No significant changes in the mechanical properties were observed due to the addition of Ti. The ductility of the experimental alloys increased positively. The best combination of mechanical and physical properties was demonstrated by AlSi5Cu2Mg alloy with the addition of 0.1 wt. % Ti.en_US
