A new neutron study of the short range order inversion in Fe${}_{1-x}$Cr${}_x$

Abstract

We have performed new neutron diffuse scattering measurements in Fe${}_{1-x}$Cr${}_x$ solid solutions, in a concentration range 0$<$x$<$0.15, where the atomic distribution shows an inversion of the short range order. By optimizing the signal-background ratio, we obtain an accurate determination of the concentration of inversion x${}_0$ =0.110(5). We determine the near neighbor atomic short range order parameters and pair potentials, which change sign at x${}_0$. The experimental results are compared with previous first principle calculations and atomistic simulations.
