A primary objective of research is physical explanation of effects of influence of the dynamic loading on mechanical properties of heterogeneous metallic alloys taking into account the mechanisms of deformation structurization and possibility of change of phase composition. The study shows that in heterogeneous aluminum-base alloys because of essential influence on their behavior in a mechanical field of the nanoparticles Al2Cu (so-called ? - a phase) and CuAl2Mg (so-called S - a phase) self-organization of structure happens to formation of hydrodynamic channels at early stages of loading. Statistical analysis of relief educations by means of the MATLAB program showed that orientation of relief bands of single crystals can be examined as criterion of critical condition of the main sample, that is testifies to testifies to approaching of it to the limit of destruction. It allows to use single-crystal films as sensors of deformation corrupting in case of plastic deformation of the principal polycrystalline samples unlike earlier offered sensors of deformation corrupting in case of plastic deformation of polycrystalline samples.5481 Product Description popup.authors Баскова Олександра Ігорівна Гаценко Олександр Сергійович Гонтарева Римма Георгіївна Гордієнко Юрій Григорович Засимчук Олена Ємілівна Ляшенко Олег Миколайович Тарасенко Лариса Василівна Турчак Тетяна Вікторівна popup.nrat_date 2020-04-02 Close
