| description | The work is devoted to clarify the physical nature of the threshold energy of shift Ed - one of the most important characteristics of the radiation resistance of materials.Physical object, on which physical and mathematical formalism Ed is constructed, is an unstable pair of «vacancy - interstitial atom», so-called dynamic defect with existence time 10-12...10-11 s.Within the law of energy conservation analytical expression for Ed is received and its structure on the basis of the analysis of the processes accompanying the subthreshold movement beaten out from atom lattice knot is established: electrostatic and elastic interaction with own vacancy of interstitial atom, and also dissipative losses of its energy at the movement in the field of an instability zone. There is a satisfactory agreement between the calculation results with the experimental data. |
