  • Abstract:

    The influence of cerium (Ce) on the as-cast microstructure and mechanical properties of
    the A-319 alloy were investigated. The A-319 experimental alloys were prepared. The
    aluminum,magnesium, cerium master alloy was added into the molten bath The cerium
    content increased 0 to 0.12 wt.% after 15 min of treatment. To obtain kinetic
    information and metallographic, samples were analyzed by using Scanning Electron
    Microscope (SEM) respectively. Dross samples were taken and analyzed by X-ray
    diffraction (XRD) for the qualitative identification of the crystalline compounds. The
    tensile properties, including ultimate tensile strength, yield strength. Elongation and
    creep properties of the as-cast experimental alloys were established. This result indicate
    that the incorporation of Ce to the A-319 alloy cause change in the morphology and
    distribution of the phase. Nevertheless, the grain size tended to be effectively refined.
    Furthermore, adding 0.12 wt.% Ce to the A-319 alloy improves the tensile properties at
    room temperature.
