Short-range ordering
Splet28. avg. 2024 · The origin of this short-range ordering is not understood nor is the relation between the short- and long-range atomic configurations. Here, we demonstrate that such heterogeneous structural disorder can be understood by application of Pauling’s rules (13, 14). These rules were established on the basis of ordered crystalline structures with ... Splet2.3 Chemical short-range order parameters Monte Carlo simulations were performed using the ATAT package.84 Most of the simulations were carried out using a cell containing 2000 atoms in the form of 10 × 10 × 10 bcc unit cells. For each composition, simulations started from a disordered high-temperature state at 3000 K.
