文摘

The influence of local lattice distortion is significant on the mixing energy and negligible on the elastic properties of HEAs. Local lattice distortion may lead to overlap of the first and second nearest neighbor shell in bcc HEAs. Alloying shows unexpected trends highlighting the importance of complex chemical interactions between constituents. The rule of mixtures can estimate first-levelly the values of the lattice parameters and elastic constants of HEAs.
