The Ability of Quantum Dots Formation in Thin Nanostructured Amorphous Films
In the last years an interest in field of quantum dots devices creating has been increased. In this work the nanocrystallite with Frank-Kasper structure was examined as the quantum dot in amorphous film. An ability to create all-inorganic Quantum Dots Light Emission Device may be considered for Tb 30 Fe 70 , Co 80 C 20 , Fe 86 Mn 13 C and Co 50 Pd 50 films. The self-organisation of atomic structure in Tb 30 Fe 70 , Co 80 C 20 , Fe 86 Mn 13 C and Co 50 Pd 50 films, which possess large values of perpendicular magnetic anisotropy (PMA) constant (K β₯ ~ 10
erg/cm
), were investigated by methods of electron diffraction and transmission electron microscopy, including the method of bend contours. The crystallization of the films proceeds in an explosive way forming different dissipative structures from initial nanocrystalline state. In previous works [2, 3] it was shown that after crystallization (Π’ ann ~ 260-330 Β°C) the atomic structures of Tb 30 Fe 70 , Co 80 C 20 , Fe 86 Mn 13 C and Co 50 Pd 50 films are tetrahedrally close-packed Frank-Kasper structures. In this work the structural model of thin film at mesoscale and its correlation with magnetic and optical properties is proposed.Π ΠΏΠΎΡΠ»Π΅Π΄Π½ΠΈΠ΅ Π³ΠΎΠ΄Ρ Π±ΠΎΠ»ΡΡΠΎΠΉ ΠΈΠ½ΡΠ΅ΡΠ΅Ρ ΠΏΡΠΈΠ²Π»Π΅ΠΊΠ°ΡΡ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ, ΡΠ²ΡΠ·Π°Π½Π½ΡΠ΅ Ρ ΡΡΡΡΠΎΠΉΡΡΠ²Π°ΠΌΠΈ, ΡΠ°Π±ΠΎΡΠ°ΡΡΠΈΠΌΠΈ Π½Π° ΠΊΠ²Π°Π½ΡΠΎΠ²ΡΡ

Regularities of Formation of the Ordered Structures in Refractory Metals at Ion Implantation
Is shown, that the character of structural - phase transformations in tungsten and tantalum at ion
implantation by the elements of the interstitial phase is defined, in the main, by the size factor, i.e. by
the ratio of the atomic sizes of implanted elements and atoms of metal. The researches are carried out

The Study of the Fine Structure of Ti-Al Coatings on the Surface of Ti, Obtained by Mechanical Alloying
The work is devoted to the study of structural-phase transformations in composite coatings (Ti-Al)+Ti during mechanical alloying. The data on the structural-phase states of (Ti-Al)-Ti coatings after mechanical alloying have been obtained, confirming the mechanism of formation of the modified layer due to deformation compaction of powder particles on the titanium surface under mechanical action. As a result of mechanochemical fusion, a TiAl3 phase with a bcc lattice (I 4/mmm structure) was detected, which corresponds to the stable state of the TiAl3 alloy. Under conditions of mechanical alloying of the structure, I4/mmm transforms into the L12 structure, which corresponds to the metastable state of TiAl3
