Results of scientific activity:
- With the use of the complex of modern physical methods of investigation (transmission and scanning microscopy, optical microscopy, backward Rutherford scattering, thermal-desorption spectrometry and others) systematic study of mechanisms of damage of surface of nickel, iron, chromium, tungsten and stainless steel under irradiation by helium ions with energy 0,02…1,8 MeV was performed.
- Influence of different ions implantation on crystalline structure of metals and alloys is studied for reveal of mechanisms of second phase nucleation and also of mechanisms of phase transformation under production in metals of hydrides, carbides, nitrides and oxides. It is shown that irradiation of films of transition metals doesn’t produce the transformation of its crystallographic structure: structure transformations proceed only under irradiation by ions of chemically active elements and produced structures depends on chemical nature of implanted ions.
- Processes of interaction of point defects with implanted impurity atoms are investigated by methods of channeling and mathematical modeling. Atomic configurations of complexes Xe with point defects are determined. It is shown that the important factor of formation of split vacancy-impurity complexes is the size factor and kind of interatomic potential (chemical bond).
- Influence of pulsed fluxes of hydrogen, helium and hydrogen-helium plasma with specific power 2…3 Mvt/cm2 on mechanical properties of austenitic stainless steels Cr16Ni15Mo3B and 18CrNi10Ti is investigated. Mechanical tensile tests have showed that irradiation up to doses ≈10.18 cm-2 produces 1,8 higher hardening of specimens and 2,3-2,7 decrease of their ductility. The change of mechanical characteristics is caused by development of cell structure.
- Abnormal hydrogen permeability of nickel, chromium-nickel and manganese austenitic steels, nucleation and growth of cracks in materials on depths exceeding much ion path is revealed.
- During the last years investigation of accumulation, of depth distribution are in progress also as study of thermal activated release of helium and hydrogen, kinetic of helium porosity development in analogous and structure materials of power plants during post implantation annealing ; the void growth “in situ” was observed on registration of all stages of this process by video technique, measurement of thermal desorption spectra (TDS) obtained on linear heating of specimens after ion implantation, study of distribution profiles of implanted particles concentration by the material depth (occurrence profiles),determination of position of implanted atom by the method of back scattering of channeled ions.
