ENG: The Severe Plastic Deformation (SPD) of the powder mixture is studied using the High Pressure Torsion method. Using the example of a mixture of aluminum, titanium and carbon powders, it is shown that SPD leads to accelerated mass transfer, which is expressed in an increase in the effective diffusion coefficient by more than 6 orders of magnitude. A hypothesis regarding the physical causes of this effect is put forward and substantiated
