This paper deals with influence on segregation of iron based phases on the secondary alloy AlSi7Mg0.3 microstructure by chrome. Iron is
the most common and harmful impurity in aluminum casting alloys and has long been associated with an increase of casting defects. In
generally, iron is associated with the formation of Fe-rich phases. It is impossible to remove iron from melt by standard operations, but it is
possible to eliminate its negative influence by addition some other elements that affect the segregation of intermetallics in less harmful
type. Realization of experiments and results of analysis show new view on solubility of iron based phases during melt preparation with
higher iron content and influence of chrome as iron corrector of iron based phases. By experimental work were used three different
amounts of AlCr20 master alloy a three different temperature of chill mold. Our experimental work confirmed that chrome can be used as
an iron corrector in Al-Si alloy, due to the change of intermetallic phases and shortening their length.
This paper deals with influence of chrome addition and heat treatment on segregation of iron based phases in the secondary alloy
AlSi7Mg0.3 microstructure by chrome and heat treatment. Iron is the most common and harmful impurity in aluminum casting alloys and
