Changes in the characteristics of the fine structure of the ChS-68 steel under neutron irradiation

详细

On the basis of the results of X-ray diffraction and microscopy studies of ChS-68 austenitic steel after neutron irradiation at 370°C with doses up to ~2 dpa, a statistical analysis of experimental data was carried out; a linear model of the dependence of the γ-Fe crystal lattice parameter of the solid solution on the elemental composition and radiation dose was developed. Contributions of the elemental composition and damaging dose in the solid solution to changes in the lattice parameter were estimated in the framework of the model.
