In this work, the results of research concerning application of rheocasting process for piston alloys structure and properties improvement have been shown. The procedure of stirring the melt by a plate stirrer at different speeds (rpm): 500, 1000 and 1500 was used. The influence of mechanical stirring effect on morphology and distribution of primary phases (- Al i Si) was tested in the hypereutectic Al-18wt%Si alloy. Test results showed a positive influence of melt stirring speed on the structural change of the tested alloy in comparison with the structure of samples obtained by a conventional casting procedure. The effects of a structural change are optimised at the melt stirring speed of 500 rpm.
