On the base of a critical analysis of existing models for nucleation of new phase precipitates in metastable binary alloys, a new kinetic model of homogeneous nucleation and growth of non-stoichiometric α ^\prime -phase precipitates (of variable composition) in Fe-Cr alloys was developed within the framework of the Reiss kinetic theory of binary nucleation. The model was further modified to account for the influence of ballistic re-solution on the kinetics of nucleation and growth of α ^\prime precipitates, following the general approach proposed in Part 1 (Zh. Eksp. Teor. Fiz. 169(4) (2026)). The model was used for qualitative interpretation of the results of recent tests, in which the stability of α ^\prime precipitates in Fe-15Cr alloys under irradiation was studied. Keywords}: nucleation theory, kinetic theory, irradiation effects, non-stoichiometric precipitates, precipitation in Fe-Cr alloys
