Résumé
Cet article récapitule les résultats de l'application des techniques de diffraction à l'etude de la structure atomique des joints de grains. La détermination de la structure de la projection d'un joint [001] à grand angle de torsion est décrite. L'influence de la nature du métal c.f.c. et de la liaison sur la structure du joint est étudiée. S'appuyant sur les résultats des études de diffraction, les auteurs proposent des généralisations concernant les structures des joints [001] à grands angles de torsion.


Abstract
The results of the application of diffraction techniques to study the atomic structure of grain boundaries are reviewed. The determination of the projected structure of a large angle [001] twist boundary is described. The influence of f.c.c. metal type and bonding type on boundary structure is examined. Generalizations are made concerning the structure of large angle [001] twist boundaries based on the results of the diffraction studies.
