چکیده انگلیسی
The migration of a grain boundary system with ridges of the first order is studied. A theory of steady-state motion of a grain boundary half-loop with facets and ridges is elaborated. The shape and properties of a moving grain boundary which contains additional structural elements (curved segments, facets and ridges of the first order) are addressed. The major kinetic parameters (mobility and its activation enthalpy) of a “rough-to-rough” grain boundary ridge of the first order were measured. It is shown that the steady-state motion of a boundary half-loop with facets and ridges complies with the principle of maximum rate of free energy dissipation.
