The Influence of annealing conditions on microstructure of AlSiCuMgFe alloys

Popis výsledku v původním jazyce

Abstract Iron is the most problematic element in recycled aluminum alloys. Significant decrease of the mechanical properties of alloy was observed if the iron content is too high. There is neither economical method nor technological process allowing to remove iron from the alloy or at the least to reduce the iron content in the aluminum alloys significantly. The influence of thermal history on microstructure of alloy was studied in this work. Sequential transformation of intermetallic phases with plate-like morphology into a more compact - polyhedral phases take place during the annealing between solidus and liquidus temperatures. These phases have tendency to settle to the bottom of the vessel. Significant decrease of the iron content in alloy above the settlement was found. The influence of annealing temperature between the solidus and liquidus on the microstructure of alloy and chemical composition of present intermetallic phases was shown.
