A Volterra-Type Dislocation Model of a Low-Angle [001] Twist Boundary in an F.C.C. Crystal

Abstract

A Volterra description is used for the displacement fields of [001] twist boundaries in f.c.c. crystals in both, the isotropic and anisotropic elastic cases. A method is used to correct for nonlinear effects associated with the finite lattice rotations of two halves of a single crystal imposed in producing the boundary. Resultant diffraction patterns calculated from the displacement fields are in good agreement with experiment. [Russian Text Ignored].
