| The structure and phase composition of dispersion-strengthened composite materials based on the AlMg system at various stages of mechanical alloying were studied by the methods of optical and scanning electron microscopies, electron probe microanalysis and X-ray diffraction analysis. A possibility of the efficient use of commercial scrap of Al alloy chips and initially large strengthening ceramic particles as the base of composite materials was shown, as well as a possibility of synthesis of strengthening particles. These materials resulted in a homogeneous dispersed structure after mechanical alloying. |
