Site occupancy and lattice parameters in sigma-phase Co-Cr alloys.

Neutron powder diffraction was used to study the distribution of Co and Cr atoms over different lattice sites as well as the lattice parameters of sigma-phase compounds Co(100 - x)Cr(x) with x = 57.0, 62.7 and 65.8. From the diffractograms recorded in the temperature range of 4.2-300 K it was found for the five crystallographically independent sites that A (2a) and D (8i) are predominantly occu...

Phase separation of a multiple occupancy lattice gas

A binary lattice gas model that allows for multiple occupancy of lattice sites, inspired by recent coarse-grained descriptions of solutions of interacting polymers, is investigated by combining the steepest descent approximation with an exploration of the multidimensional energy landscape and by Gibbs ensemble Monte Carlo simulations. The one-component version of the model, involving on site an...

Total energy of sigma-phase Fe–Cr–X (X=Co, Ni) alloys: Calculated and modeled data

The article contains computational data of electronic structure and crystal stability of two sigma-phases, namely Fe-Cr-Co and Fe-Cr-Ni, using the Korringa-Kohn-Rostoker method (KKR) for electronic band structure calculations. Total energy values, ET , calculated for the number of ordered unit cells with various atomic concentrations and sublattice occupancies are reported. In parallel, obtaine...
