It was ascertained, that overheating the AlSi17Cu5Mg alloy aids the modification, resulting with microcrystalline structure. Uniform arrangement of the Si primeval crystals in the warp, and α(Al) solution type, supersaturated with alloying elements present in the base content (Cu, Mg) assures not only increased durability in the ambient temperature, but also at elevated temperature (250o C), what is an advantage, especially due to the use in car industry.}, type={Artykuły / Articles}, title={Structure and Mechanical Properties of AlSiCuMg Alloy after Thermo Processing}, URL={http://www.czasopisma.pan.pl/Content/88429/PDF/14_paper.pdf}, doi={10.1515/afe-2015-0014}, keywords={mechanical properties, Hypereutectic Al-Si alloys, Overheating, Modification with CuP10 master alloy, Microstructure}, }
