Oa. Bannykh et al., NEUTRON-DIFFRACTION STUDY OF ATOMIC ORDERING IN THE ALLOYS OF PSEUDOBINARY SECTION OF NIAL - FEAL AND NIAL - COAL SYSTEMS, Russian metallurgy. Metally, (3), 1995, pp. 64-68
Due to X-ray-diffraction and neutron-diffraction analyses of ternary i
ntermetallic compounds belonging to the pseudobinary section NiAl - Co
Al, it was established that one sublattice is occupied by only aluminu
m atoms and another sublattice is occupied by randomly distributed Ni
and Co atoms. The experimental results are adequately described by a m
odel of random distribution of Ni and Fe atoms in one sublattice. No s
hort-range order is revealed in (Ni,Fe) and (Ni,Co) sublattices.
