We studied the dissolution of zirconium in the molten alloy AlMg6Mn1. Zirconium is introduced into the melt in the form of the ligature AlZr2. It is established that during 10 minutes at 750 °C complete Zr dissolution occurs. The study of the structure and phase composition of the samples allowed setting the dendrite structure of the samples; presence of clusters of magnesium, manganese, iron and silicon in the interdendritic space. Zirconium is injected into the melt in a stable particulate form (D023) Al3Zr phase is uniformly distributed in grains α - Al as a metastable (L12) Al3Zr phase. After some time, increasing of the density distribution of the metastable (L12) Al3Zr in the aluminum matrix phase is detected in the selected samples after 10 and 60 minutes after the introduction of zirconium. It has been established that after some time, an increase of the aluminum lattice parameter occurs in the samples selected after the addition ligature of zirconium.
