Microstructure Characterization of Rapid Solidification Al Alloy Foil
The AlMn and AlMnSi foils were fabricated by rapid solidification technology.The phase transformation temperatures,microstructures and distribution of elements were characterized by Differential Scanning Calorimetry (DSC),Transmission Electron Microscope (TEM),X-ray Diffraction (XRD) and Energy Disperse Spectroscopy (EDS) respectively.The result shows that the phases of AlMn7 nanofoil conclude Al,Al6Mn and quasicrystal phase,the crystal size is about 120nm; the phases of AlMn5Si5 nanofoil conclude Al,Al4.01MnSi0.74 and Al9Mn3Si,the crystal size is about 60nm.The phase transformation temperatures of AlMn7 and AlMn5Si5 nanofoils are 543K and over 873K,respectively.The microstructure morphology of AlMn7 nanofoil are rod,block and petal-like,but the microstructure morphology of AlMn5Si5 nanofoil is homogeneous globular.
