| The mechanical properties of hypoeutectic silumins can be improved through chemical modification as well as chemical elements or technological processing. This study presents the results of modification of an Al-9%SiMg alloy with aluminium, boron, and titanium. The experiments were conducted following a factor design 23 for 3 independent variables. The influence of the analyzed modifiers on the microstructure and mechanical properties of the processed alloy was presented in graphs. The modification of a hypoeutectic Al-9%SiMg alloy improved the alloy's properties. The results of the tests indicate that the mechanical properties of the modified alloy are determined by the components introduced to the alloy. |
