ENERGY OF A NONREGULAR HEXAGONAL NETWORK OF MISFIT DISLOCATIONS IN ANISOTROPIC ELASTICITY - THE CU FE HETEROINTERFACE/

The elastic energy per unit surface associated to a non-regular hexago nal network of misfit dislocations lying along a planar interface is e xpressed analytically for any two anisotropic crystals. The present ex pression generalizes recent results only valid for a regular hexagonal network formed by dislocations of the same kind of Burgers vectors. I t takes into account the specific cut radius associated to each disloc ation segment. A numerical application is presented for dislocation ne twork observed at the Cu/Fe interface.
