Plastic deformation can produce materials with different structural states. Strained BCC-metals have been shown to undergo internal structural developments during plastic deformation. The interaction between quasi-cleavage crack and substructure was studied. The details of the influence of substructure on stress near the crack tip, structure rebuilding near the crack tip and the energy of dislocation movement were analyzed. The essential influence of the deformation substructure on the force and energy parameters of fracture processes was established.
