Arrangement and density of geometrically necessary dislocations at the scale of strain-induced substructure of copper deformed in tension

Orientation dependent dislocation substructure evolves inside grains of polycrystalline copper during tensile deformation, together with the development of two-component texture. In order to study peculiarities of dislocation arrangement and quantify the geometrically necessary component of dislocation density at the scale of substructure, a thin foil ...
