The Ti additions were in proportions of 0.1, 0.2 and 0.3 wt.% Ti. The casting process was carried out in ceramic molds, created for the investment casting technology. Half of the experimental samples were processed by precipitation curing T6. The measured results were compared with primary alloy AlSi7Mg0,3 and experimental alloy AlSi7Mg0.3Cu0.5Zr0.15. In variant with addition 0.1 wt. %, the tensile strength Rm increased by 1,5% but the elongation AM decreased to 40%. Variants with 0.2 and 0.3 wt. % addition of Ti achieved similar Rm but approximately 40% decrease in AM. However, it is interesting that yield strength Rp0.2 increased for all variants by approximately 14 to 20%. The results point out the possibility of developing a more sophisticated alloy for automotive industry.}, type={Article}, title={Effect of Ti on Selected Properties of AlSi7Mg0.3Cu0.5 Alloy with Constant Addition of Zr}, URL={http://journals.pan.pl/Content/117789/PDF/AMM-2021-1-09-Kuris.pdf}, doi={10.24425/amm.2021.134760}, keywords={AlSi7Mg0.3Cu0.5, Investment casting, Zirconium, Titanium, Increasing mechanical properties}, }
