Abstract:

It was determined that the number of vacancies for Ni, which are situated in 1 cu cm of the deformed metal, as well as its number of dislocations per cu cm. It was revealed that the number of vacancies produced during the deformation of material constitutes merely a few hundredths of 1 of the number of atoms, and increases linearly with an increase in degree of deformation meanwhile, the number of dislocations per cu cm increases with an increase of deformation according to a more complex law, tending toward saturation at various deformations for different materials. In all cases, at the zero-extrapolation of D, the relative volume variations and, consequently, the number of defects rising during the deformation tend toward zero.
