Abstract
We study the displacement of the boundary between the two grains of an idea l two-dimensional bicrystal having a hexagonal lattice within the plane. Th e boundary we deal with is a discontinuity straight line for the lattice or ientation function that may move at a different velocity from the underlyin g matter; hence dissipation occurs, eventually equal to the rate of release d energy. We estimate the characteristic dissipation in the propagation of the discontinuity. (C) Academie des sciences/Elsevier Paris.
