The paper proposes the hypothesis of the explosive-nature dislocation-electronic mechanism of the deformation cracks in the metals’ nucleation. This hypothesis is based on the Coulomb repulsion of the positively-charged ions. when the neutral state of the ion–electron system in the crystal lattice is disturbed that leads to the nanolocal Coulomb explosion and the appearance of the nucleated cracks.
Ключевые слова: crystal lattice, cracks, dislocations, electrons, Coulomb explosion.
