“…For most materials of modern nuclear reactors (PWR, BWR), the amount of dpa is less than 1 for 40 years of operation. However, for active elements of fast neutron reactors, the defect accumulation rate can reach more than 10 dpa/year [19]. Taking into account the calculated values of dpa, it can be asserted that the study of the TiN, TiAlN, TiAlYN, Ti x Cr 1−x N for 0.58 ≤ x ≤ 0.8, (TiHfZrVNb)N coatings with the chosen fluences of He + ions is practically important for nuclear material science.…”

Modelling of parameters of high-fluence ion irradiation of nanostructured TiN, TiAlN, TiAlYN, TiCrN, (Ti-HfZrVNb)N coatings by the Monte-Carlo method was carried out. The obtained results and proposed mechanisms of processes were experimentally proved in studying the structure of the coatings after irradiation with 500 keV He + ions in the fluence range from 5 × 10 16 ion/cm 2 to 3 × 10 17 ion/cm 2. The effect of depth localization of the maximum concentration of implanted helium on nitrogen selective sputtering from coatings as well as on partial flaking (exfoliation) of coatings was observed for the ion fluences higher than 2 × 10 17 ion/cm 2. No phase segregation of the solid solution as the main phase in the nanostructured coatings was found after the ion irradiation. No smarco-or microblistering of the coatings after ion irradiation was found, at least to a blister size approximating the nanoscale.

“…When calculating CPF depending on interactions number and particles penetration depth and also vacancy type nanoclusters concentration needs to find real result finding area. We will note the main regularities when calculating CPF depending on interactions number arising when result finding area for various flying particles and heavy targets [11][12][13][14][15].…”

“…Passing ions through substance is a difficult task as during creation physical, and mathematical models. A set of the flying particles types and targets of Mendeleev's Periodic system represents a huge elements number [9][10][11][12][13][14]. At the same time it is possible to consider various situations when the flying particles mass number are less than a target atomic number, it is commensurable with a target atomic number and a case when the flying particle atomic weight is more or much more target atomic number.…”

Creation new materials with unique properties is one of priority researches areas, both in physics, and in technique. The study of small metal particles properties from atoms hundreds and thousands is of great interest by their possible usage as materials or surface nanostructures. The fact that nanomaterial properties considerably depend on the particles properties making them is undoubted. The free clusters internal structure research could play a key role in an explanation of their physical or chemical features. Work is assigned to obtaining the regularities arising when modeling radiation processes in the heavy ions irradiated with various ions. The regularities arising when calculating cascade and probabilistic functions depending on particles penetration depth, interactions number are found. Real areas finding the radiation defects concentration result are defined, calculations for various flying particles and heavy targets in the energy range 100-1000 keV are made. Calculations results are presented in the schedules and tables form.

“…Without research in this direction, solid state radiation physics would remain a fairly academic occupation that is not of interest for practical applications [1][2][3][4][5][6][7][8][9][10][11]. A lot of works have been devoted to the problems of the interaction of particles with matter and the generation of radiation defects upon irradiation of matter with ions [5][6][7][8][9][10][11][12][13]. Most of the work in this direction is carried out as part of the cascade-probability method [14][15][16][17].…”

The paper considers mathematical modeling of radiation defect formation processes in materials under ion irradiation. Algorithms for calculating cascade probability functions (CPF) taking into account energy, spectra of primary knocked out atoms (PKA) and the concentration of radiation defects during ion irradiation loss are presented. The defect concentration was calculated for various incident particles and targets of the periodic table. The regularities of the behavior of the concentration of defects depending on various physical parameters are revealed. The calculation algorithm is presented in the form of flowcharts. The work was performed as part of the cascade-probability method, the essence of which is to obtain and further use CPF. CPFs have the meaning of the probability that a particle generated at a certain depth h' will reach the detection depth h after the nth number of collisions.
