The presented work discusses the influence of modification of AlSi10Mg alloy on its solidification kinetics during the mould cavity filling. In order to study this influence, the measurements concerning temperature changes of the modified and the non-modified AlSi10Mg alloy have been done at selected places of the mould. Thus the solidification and cooling curves have been achieved. The recorded temperature changes have served as a basis for drawing the graphs representing the flow rate of the metal stream and the distance travelled by the front of the stream against the time. An addition of modifier in the form of strontium master alloy has caused a significant shortening of the flown distance. The recorded solidification and cooling curves have also allowed for determining the temperature changes at the front of the metal stream during the mould cavity filling. Taking the achieved results into account it has been found that the modified alloy begins to solidify after having passed a distance of about the one-third of the distance determined for the non-modified alloy.
