The paper investigates the influence of a strontium modifying additive in the range of 0.05 to 0.3 wt.% on the structure formation and tribological properties of cast aluminum matrix composites based on the pseudo-binary Al – Mg2Si system (in the hypereutectic composition range). It is shown that strontium modification (0.2 wt.% Sr) of cast aluminum matrix composites Al + 15 wt.% Mg2Si leads to a reduction in the average size of Mg2Si reinforcing particles to 24 μm (by Feret diameter) with an aspect ratio of 1.28 and a particle distribution uniformity index in the cast material structure of 0.44. For a highly hypereutectic composition (25 wt.% Mg2Si), strontium modification in the same amount results in a decrease in the average size of Mg2Si particles to 44.8 μm and a change in their morphology to blocky, compact, and close to equiaxed, with a distribution uniformity index of 0.24. Further increase in the concentration of the modifying additive lead to some particle coarsening, likely due to the over-modification effect, as well as the precipitation of excess intermetallic phases with needle-like morphology. Tribological tests under dry friction conditions using a ball-on-disc scheme in conjunction with steel reveal a significant reduction in the coefficient of friction (by 25–30%) and mass wear (by more than an order of magnitude) for strontium-modified cast samples of Al – Mg2Si composites.
