Modification of the Al-9%SiMg Alloy with Aluminum, Boron, and Titanium Fast Cooled Mixtures

摘要

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 2(3) 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.
