Abstract
The investigations have been taking place on the following modified and unmodified aluminium alloys: AlSi7Mg, AlSi10Mg and AlSi12Cu. By dilatation and cooling curves, the derivate cooling curves of the cast sample and the mould (made by Croning process) the segregation of the silicon phase in the eutectic reaction has been detected respectively. The air gap between mould and cast sample, and influence of the modification on the formation of the intensive contraction have been determined.
