Structures and Mössbauer spectra of splat-cooled Al-Fe alloys

CALCULATION OF THERMODYNAMIC PROPERTIES OF Al-Fe, Al-Ni AND Ni-Fe ALLOYS USING FACTSAGE

Thermodynamic predicting analysis of three binary systems Al-Fe, Al-Ni and Ni-Fe are shown in this paper. Thermodynamic analysis involved calculation of activities, coefficient of activities, partial and integral values for enthalpies and Gibbs energies of mixing and excess energies at three different temperatures: 1873K, 1900K and 1973K, as well as calculated phase diagrams, for the investigat...

Atomistic Study of Surfaces and Interfaces of Fe-Cr and Fe-Cr-Al Alloys

Surface and interface properties of Fe-Cr, Fe-Al, and Fe-Cr-Al are studied using Exact Muffin-Tin Orbitals and Monte Carlo methods and with x-ray photoelectron and Auger electron techniques. Surface composition is investigated as a function of oxidation (heating) time. Hard x ray photoelectron spectroscopy (HAXPES) is used to scan non destructively the compositions below the surface. It is foun...

Analysis of Al-2p photoelectron spectra of alumina coatings formed on heat treated Al-containing alloys

Mössbauer diffractometry on polycrystalline 57 Fe 3

A Mössbauer powder diffractometer was used to measure diffraction patterns from polycrystalline foils of Fe3Al. The intensities of Bragg diffractions were measured as a function of the energy of the incident photon. The bcc fundamental diffractions showed large changes in intensity as the incident energy was tuned through the nuclear resonances. These variations of diffraction intensity with in...
