Structure and Properties of Mechanically Alloyed Composite Materials from Scrap of Al Alloys

Abstract:

The structure and phase composition of dispersion-strengthened composite materials based on multicomponent aluminium alloys of the Al–Cu–Mg and Al–Si–Cu–Fe systems at various stages of mechanical alloying were studied by the methods of optical, scanning electron and ion 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 during the treatment. After mechanical alloying, these materials possessed a homogeneous and disperse structure, high hardness at room and elevated temperatures and a low linear thermal expansion coefficient.
