Conduct an Investigation on Nanostructure of Al-20Si-5Fe Alloy, Produced by Melt Spinning Process and Observation of Mechanical-Metallurgical Properties, M.Sc. Thesis Sharif University of Technology ; Davami, Parviz (Supervisor)
Abstract
In this study, Al-20Si-5Fe ribbons produced by melt-spinning method. Nanostructure and growth morphology of rapidly solidified products explored using optical microscope, scanning electron microscope and x-ray diffraction. Microstructural investigations depicted two distinctive zones of featureless (faceted morphology) and dendritic. In addition, no intermetallic phases could be observed in the rapidly solidified ribbons in comparison with coarsed and needle shaped intermetallic phases of as cast alloys which it demonstrates the extension of solid solubility of Si and Fe in the matrix and consequently intermetallics formation was hindered by higher cooling rates. Subsequently, ribbons...
