| dc.description.abstract | The problem of impurity diffusion accompanied with segregation phase nucleation on dislocations has been considered using the approximation of the local equilibrium with respect to the impurity distribution between the matrix solution and the near-dislocation regions. It has been shown that the known experimental data on diffusion and solubility of interstitial impurities (C.~I •.•• etc.) in sorim metals (a-Fe;' Nil and alloys [Fe-3.5% Si, Fe-0.16%C [steel)) are :described in the frame vlOrk of the dislocation trap \Oodel, the only case where some segregation phases with negligible diffusion conductivity and high capture ~bility for impurities in the near-dislocation regions are nucleated. The characteristics of the segregation phase regions near-dislocations have been obtained from the treatment of the diffusion and solubility data. On the basis of the crystallographic and thennodynamic considerations it has besn shown that the existence of such ~egregation phase regions along dislocation in the systems . in question is possible | en_US |
