abstract = {High entropy alloys show a variety of fascinating
properties like high hardness, wear resistance, corrosion
resistance, etc. They are random solid solutions of many
components with rather high concentrations. We perform
ab-initio calculations for the high entropy alloy CrFeCoNi,
which equal concentration of $25\%$ for each element. By the
KKRnano program package, which is based on an order-N
screened Korringa–Kohn–Rostoker Green’s function
method, we consider a face-centered cubic (FCC) supercell
with 1372 randomly distributed elements, and in addition
also smaller supercells with 500 and 256 atoms. It is found
from our calculations that the local moments of the Cr atoms
show a large environmental variation, ranging from −1.70
μB to +1.01 μB with an average of about −0.51 μB. We
present a new method to calculate “local energies” of
all atoms. This is based on the partitioning of the whole
space into Voronoi cells and allows to calculate the
energetic contribution of each atomic cell to the total
energy of the supercell. The supercell calculations show
very large variations of the local energies, analogous to
the variations of the local moments. This shows that the
random solid solution is not stable and has a tendency to
form an L12-structure with the Cr-atoms ordered at the
corner of the cube and the elements Fe, Co, and Ni randomly
distributed on the three other FCC sublattices. For this
structure the variation of the local moments are much
smaller.},
