Abstract: In accordance with the orientation ratio (110), [001]$\beta$ || (111), [1$\bar10$]$\alpha$ established by fast electron diffraction between the ordered $(\beta)$ and disordered $(\alpha)$ phases in the foil of a Pd + 57 at.% Cu solid solution, the atomic structure of the interface is modeled by molecular dynamics. It is found that the structural and size discrepancies are compensated by interfacial dislocations with Burgers vectors $a/2 \langle111\rangle$ in coordinates of the $\beta$-phase.

Keywords: interface, molecular dynamics, interfacial dislocations, orientation ratio.
