Abstract

The functions of interatomic interactions for Fe-H system in the embedded-atom method approach have been shown. The potential functions for pure iron reveal the properties of low-temperature bcc- and high-temperature fcc-phases that are important when simulating processes of the Fe-H systems deformation. Semiempirical potential of Fe-H interaction was satisfactorily fitted to a number of properties of perfect α-Fe system with H impurity.
