RESEARCH TASKS IN PHYSICS AS A MEANS OF FORMING THE RESEARCH COMPETENCE OF A FUTURE ENGINEER ^{[№ 4 ' 2020]} One of the most important tasks of higher education is to create conditions for training highly qualified engineering and technical personnel who are ready not only to master and improve existing technologies, but also to develop new hightech technologies. The basic basis for training such specialists can be practical and seminar classes in the course of physics, aimed at solving research problems, in conjunction with the corresponding independent work of students. Solving research problems: contributes to a deeper understanding of the physical processes and phenomena underlying modern hightech technologies; allows you to understand the conditionality of modern technologies by physical laws and laws; develops skills to structure information about technical objects and technological processes in a logical sequence; forms a General idea of the sequence of solving a technological problem (setting goals, formulating hypotheses, planning and conducting experiments, analyzing results and conclusions). Since physics is studied in all engineering specialties, it would be advisable to start implementing this approach as part of the physics course, especially since there is a huge stock of tasks that can be offered to future engineers for solving both in seminars and practical classes, and as homework.

ON THE QUESTION ON THE STATISTICAL COMPARISON OF ACCURATE DISCRETE BREEZERS WITH QUASIBREEZE MODEL SOLUTIONS OF A_{3}B STEHOMETRY CRYSTAL ^{[№ 5 ' 2018]} The method of molecular dynamics is used to perform a statistical comparison of exact discrete breathers with quasibreather model solutions of the A3B stoichiometry crystal, using the example of Pt_{3}Al. A phonon spectrum of this model crystal is obtained, the dependences of the rootmeansquare deviation, the coefficient of variation, and the mean frequency of the model quasibreather on the time of its existence are obtained. Also within the framework of this model, the following statistical characteristics and dependencies were calculated: a grouped statistical series of absolute and relative frequencies, a polygon of absolute and relative frequencies, a histogram of relative frequencies, an empirical distribution function, an estimate of the mathematical expectation and variance of the original sample. Analysis of statistical data allows us to conclude that in the model under consideration using the interatomic interaction potential obtained by the immersed atom (EAM) method, the quasibreather solution differs slightly from the exact breather solution.Moving discrete breather interactions with the point defect in crystal with A_{3}B composition taken as an example Pt_{3}Al are studied by the method of molecular dynamics.

COOPERATIVE ATOMIC DISPLACEMENTS NEAR INTERPHASE BOUNDARIES NIγFE ^{[№ 6 ' 2016]} By method of molecular dynamics studied the cooperative atomic displacements near the interface a bimetal solidphase contact NiγFe. The differences in the behavior of the Ni and Fe atoms with their participation in the process of mass transfer across borders is established. Currently still a lot of unresolved issues related to the atomic structure of interfaces and mechanisms of their interaction with a variety of defects generated by, for example, by radiation exposure. In particular, special interest is the cooperative atomic displacements near the interphase boundaries and their contribution to the transport of energy and mass. It is shown that the introduction of interstitial atoms near the interface can cause a cooperative atomic displacements that lead to the climb of misfit dislocations. All cooperative atomic displacements proceeded on crowdions mechanism along the packed rows. The differences of behavior of atomic displacements on the number of interstitial atoms, and their type. The differences in the behavior of atoms, apparently, due to the high binding energy of the type NiγFe compared with connections type γFeγFe, resulting in the Fe atoms are more mobile than the Ni atoms and penetrate through the interface is much more intense. Such activity of Fe atoms near the interface NiγFe border creates the preconditions for the consideration of such phenomena in the boundary as the basis for the creation of new materials with specific desired properties.

MOVING DISCRETE BREATHER INTERACTION WITH THE POINT DEFECT IN THE CRYSTAL WITH A_{3}B COMPOSITION ^{[№ 3 ' 2016]} Moving discrete breather interactions with the point defect in crystal with A_{3}B composition taken as an example Pt_{3}Al are studied by the method of molecular dynamics. The problem of interaction the objects of soliton with topological defects in the crystal is important for assess the prospects of the use of such solitons, as discrete breathers, in technological processes. As a point defect interstitial Al atom is, placed into the tetrahedral cavity of the crystal. To make excitation of the moving discrete breather two Al atoms were deviated from their equilibrium position on the value of 0,5–1 A and 1 A to the opposite sides along the densely packed directions this way the initial velocity of the discrete brearher moving through the crystal. Moving discrete breather excitation is possible along the densely packed directions: <110>, <011>, <101>, <110>. In the chosen model several atoms of the light sublattice participate in the moving discrete breather oscillations.In this case moving discrete breathers can migrate through the crystal at a considerable distance, almost without dissipation its energy. The obtained data allow us to judge about moving discrete breather influence on the point defect in the crystal due to its speed, energy and the distance to the defect. This opens up a prospect of usage such objects as analyzer of alloy purity and defect structures in the crystals with A_{3}B composition. Moreover such objects can be used to transfer energy or information along the crystal.

BEHAVIOR OF THE QUASIBREATHER MODE IN PT_{3}AL CRYSTAL WITH THE POINT DEFECTS ^{[№ 9 ' 2015]} Nowadays the localized oscillations of the atoms or separate atomic groups are being studied in the perfect chips what makes the usage of the acquired results more difficult when studying the real crystals with the deffects. In this researсh by the method of molecular dynamics we study influence of the point defects on the quasibreather mode behavior in stoichiometry crystal A3B using Pt_{3}Al as an example. As point defects there are divacancies, trivacancies Pt in the crystal of Pt_{3}Al as well as interstitial atoms of Al that are placed into the tetrahedral vacuums. The considered model is a bulk stoichiometry crystal A_{3}B, where the atoms interact through Morse pair potential. It was found that point defects within Pt_{3}Al alloy substantially influence on the quasibreather mode in the case of their close arrangement. The exposure is in the highamplitude localized oscillations destruction with the further energy dispersion through the crystal. But it's worth to remark that while highamplitude oscillations degradation dispersion predominantly takes place into Al sublattice where the energy stays localized because of the forbidden band availability in the phonon spectrum of Pt_{3}Al crystal during the long period of time. Besides it's established that there is a quasibreather mode extended stability region near Pt divacancy and trivacancy. In the event of the observing at the point defect in the form of the interstitial Al atom, that is implantated into the tetrahedral vacuum such region does not exist. The acquired results should be counted while investigating the features and qualities of the real stoichiometry crystals А_{3}В.
