TEM OBSERVATION ON MICROSTRUCTURE OF RAPIDLY SOLIDIFIED Al-Fe-V-Si-Zr-Ti ALLOY POWDERS

    Graphical Abstract
    • Abstract
  • A new Al-Fe-V-Si-Zr-Ti alloy is designed based on the aluminum alloys of Al-Fe-V-Si and Al-(Zr,Ti,V) systems. The ultrasonic gas atomized powders below 61 μm have been investigated by TEM. There are two types of spherical phases and cellular structure found in the powders below 40 μm. The lamellar structure could be observed in the powders from 50 to 61 μm. The microstructures of the powder particles below 61μm consist mainly of Al12 (Fe,V)3Si and Al3(Zr,Ti,V) dispersoids and a small amount of lamellar structure.
