SOME QUESTIONS OF PHYSICS OF STRENGTH OF METAL NANOSTRUCTURES

Abstract

In the work of the equation is obtained that relates the limit of fluidity of a crystal with its limit of elasticity. The equation is analogous to the known equations of the Hall-Petch. It is shown that, beginning with the critical size of nanocrystal, increase its hardness is replaced by the opposite effect. For a number of metals are given the value of the critical size of nanocrystal.
