Precipitation Behavior of the Spray-deposited Al-Si-Fe-Mn-Cu-Mg Alloy

    Graphical Abstract
    • Abstract
  • The aging process of the spray-deposited Al-20Si-5Fe-3Mn-3Cu-1Mg alloy was investigated by DSC analysis, microhardness measurement, TEM and HREM observations. The results show that two kinds of precipitates, S-Al2CuMg and σ-Al5Cu6Mg2 precipitate from matrix and improve the tensile strength of the alloy efficiently at both the ambient and elevated temperatures (300℃).
