The Application of X‐ray Diffuse Scattering to the Calculation of the FeAl Equilibrium Diagram

Abstract: Absolute intensity measurements of diffuse X-ray scattering on single crystals of disordered equilibrium Fe-A1 alloys are made at (000), ( l l l ) , and ($ f +) points of the reciprocal lattice of b.c.c crystals. These measurements give the opportunity of obtaining thethrffi corresponding Fourier transforms of the interchange energies. According to Khachaturyan's theory these Fourier transforms are the energetic parameters which completely determine the thermodynamics of Fe-A1 alloys in a self-consistent field… Show more

“…According to [56][57][58][59][60][61], the configuration entropy of the magnetic subsystem (i.e. moments with the spin numbers s α = 1/2, 1, 3/2, 2 or 5/2, …) in the long-range ordered magnetic states such as the ferromagnetic or ferrimagnetic ones can be presented within the scope of the correlationless (MSCF) approximation as follows [56][57][58][59][60][61][62][63][64][65]:…”

“…In order to express the total 'mixing' energies in the explicit form as a function of temperature, one can consider a simplest interpolation model for approximate estimation. Thus, according to [65] (see also a set of quite similar representations in [62][63][64]), the temperature dependence of the spontaneous magnetization in Eqs (11) for α-th (α = Ni, Fe) subsystem of atomically disordered alloys based on a cubic Bravais lattice at certain composition can be presented by the approximate relation:…”

“…(v) the second aspect is the interdependence of magnetism and spatial LRO or decomposition (segregation) reactions, which occur in these alloys [2,59,61,62,95]. The need to incorporate the both 'chemical' and magnetic interactions (with a strain-induced contribution) within any complete model of f.c.c.-Ni 1−c Fe Fe c Fe alloy (c Fe -relative concentration of Fe) has been indicated in many earlier studies.…”
