Modeling of radiation-induced segregation in Fe-xCr-8Ni and Fe-20Cr-yNi alloys (with specific values of x and y) for the corresponding vacancy migration energies has been carried out. Method of profiling the sample in depth, based on the use of the PIXE method, has been modified. The stress-strain state of an elastic material with a crack at the boundary of the connection with a rigid base under the condition of contact interaction of the crack edge with the inclusion and the base has been studied. The model of multiphase diffusion consisting of alternating phases of local Brownian fluctuations and ballistic relocation has been investigated. A phase method for the analysis of the positron lifetime spectrum has been developed. It has been shown that the statistical spread of the parameters for it is much smaller than the spread obtained by the method of least squares.
