Abstract

The atomic structure of Ni – Al, Cu – Au, Ni – γFe interface boundaries, oriented along planes (100) and (111), and diffusion mechanism along it in solid-contact were studied by the method of molecular dynamics. It was shown that on the boundary forming a net of edge misﬁt dislocations, which play key role in diffusion along interface boundary.

Highlights

The atomic structure of Ni –Al, Cu –Au, Ni – γFe interface boundaries, oriented along planes (100) and (111), and diffusion mechanism along it in solid-contact were studied by the method of molecular dynamics
In [5], in the study by computer simulation of diffusion along the Ni –Al interphase boundary in two-dimensional model was found that misfit dislocations play a key role in the migration of atoms near the boundary
The present work is devoted to the study of the atomic structure of Ni –Al, Cu –Au, Ni – γFe interphase boundaries and diffusion mechanism along them in the condition of solid phase contact by the method of molecular dynamics

Summary

Introduction

The atomic structure of Ni –Al, Cu –Au, Ni – γFe interface boundaries, oriented along planes (100) and (111), and diffusion mechanism along it in solid-contact were studied by the method of molecular dynamics. In [5], in the study by computer simulation of diffusion along the Ni –Al interphase boundary in two-dimensional model was found that misfit dislocations play a key role in the migration of atoms near the boundary.
