In the paper on the basis of the theory of metal plastic deformation there are obtained analytical de-pendences of dislocations critical density and cycle number up to destruction caused by factors technological impact upon the surface under working.
For the first time in complex there are taken into account such physical characteristics as an effort, temperature and speed of deformation in the area of cutting and strengthening.
A tie between such parameters of surface layer state as a steel grain size and dislocations density is defined.
