Abstract: The article deals with the detected features of the changes on heating and cooling of the linear dimensions of samples alloy of aluminum-silicon during heat treatment and thermo-cyclic processing. We show that the anomalous effects in the expansion-compression cast samples containing eutectics due to the continuous violation of continuity of the eutectic dual crystal. It was found that this process occurs at a temperature of 410-420 º C. The division of the eutectic crystal and subsequent transformation in a form sphere and coagulation processes lead to the formation of granular structures result in.
