The results of investigation of structure evolution of powder composition of Fe/SiC during mechanical activation (MA) are described. It is shown that the mechono-composite Fe/SiC is formed by treatment of the composition of Fe/SiC powders in the mill with energy intensity of I = 3 W/g during a short time. The main stages of microstructure formation of the composite Fe/SiC powders include crushing, deformation mixing, submicrostructure fragmentation of components and forming of globular microstructure. The alignment of the phase composition and size range of the particles of mechano-composites Fe/SiC and SiC inclusions takes place during 60 minutes of the MA. The SiC particle size is decreased from 40–180 microns to 0,3–2 microns. The formation of the Fe/SiC composite by MA during 60 minutes occurs without significant interaction between the components.
