An extended structural ledge description of heterophase interfaces
Tóm tắt
A two-dimensional atomic scale geometric description of general heterophase interfaces is presented on the basis of an extension of the structural ledge theory and of the near coincidence lattice concept. From the orientation relationship and the lattice parameters of the two crystals forming the interface, two different types of ledges and their related terrace can be derived. Then, these two ledges, structural and faulted, are used as unit elements, for the reconstruction of any type of interface with a minimum of lattice strain featured on the habit plane. This analysis contributes to the discussion of the ledge versus dislocation structure at interfaces with a large misfit.
