Influence of Ca, Sb and Heat Treatment on AlSi9CuMnNi Alloy in Frame of Their Structure
2018
Treatment of metal alloys is one of the ways to affect the quality and properties of the material at the Faculty of Mechanical Engineering of the Jan Evangelista Purkyně University in Usti nad Labem, one part of the research consists of searching for the influence of various modifying and inoculating elements on selected aluminum alloys. One of the alloys undergoing the present research is the hardening aluminum alloy AlSi9CuMnNi. The article describes one from these experiments. AlSi9CuMnNi alloy was modified with various amounts of calcium (0.05, 0.1 and 0.15 wt% Ca) and 0.2 wt% Sb. The alloy without modification and with 0.2 wt% Sb was heat-treated, too. In the experiment were made three castings for each type of alloy. The final structure of each casting was analyzed.
