The structure of Al-based composite materials obtained by low-energy grinding in a vibratory mill, pressing and sintering in a protecting gas atmosphere was studied with scanning electron microscopy and X-ray phase analysis, depending on the amount of magnesium additives. It is established that the grain size of the matrix decreases as the crystal size reduction with an increase in the magnesium content in the material.
