This paper considers the possibility of fabrication of the composites based on silumin A356 ($\cong$ 7% wt. Si, 0.4% wt. Mg, etc.), using casting with the addition of quasi-crystalline Al$_{65}$Cu$_{20}$Fe$_{15}$ (45% wt. Al, 38% wt. Cu, 17% wt. Fe) particles into the melt pool and subsequent treatment of the melt in a magnetohydrodynamic (MHD) plant. As shown, the addition of 8%wt. of Al$_{65}$Cu$_{20}$Fe$_{15}$ powder provides optimal parameters of the treatment in the MHD plant and enables production of composite material, whose hardness is higher by 70% than that of the initial A356 alloy. The influence of heat treatment and severe plastic deformation on the structure and properties of the obtained alloy is analysed. Mechanical properties of A356—Al$_{65}$Cu$_{20}$Fe$_{15}$ composites at elevated temperatures are studied.

Key words: silumin, composite, severe plastic deformation.
