Abstract
The site occupancy in the Re-W sigma phase is studied using neutron-diffrac tion experiments and using a first-principles statistical thermodynamics ap proach. We show that the five inequivalent lattice sites of the sigma phase display a specific site-occupation sequence with increasing W composition which is explained by a theoretical analysis.
