Аннотация: The process of dendritic crystallization of Co and Fe films is investigated. Electron-diffraction methods show that fractal growth of dendrites in Co and Fe films proceeds by multiple twinning of the elements of a nanostructure consisting of different clusters with close-packing. The formation of superstructures is explained by a shell model of a cluster structure forming nanocrystallites. (C) 1997 American Institute of Physics.

Аннотация: A structure formed in nanocrystalline iron-carbon films exposed to an electron beam was studied. Explosive crystallization (EC) with the formation of dendrite and cellular-dendritic instabilities at a rate of up to 1 cm/s was observed. It was shown that the dependence between the growth rate of dendrite branches (or cells) during EC and the rounding radius of dendrite branch tips can be approximately described by equations used to calculate the crystal growth in supercooled melts. To explain the EC mechanism, a model of a liquid zone formed at the crystallization front was used. It was shown that the liquid zone arises due to energy accumulated in the film in the nanocrystalline state. It was assumed that this energy was accumulated due to the energy of elastic stresses.

Аннотация: The importance of studying Fe-Mn-C alloys is related to their wide use as constructional materials in mechanical engineering. In this work an effort has been made to elucidate the physical origin of the magnetization in austenitic steels by calculating the electronic structure of grain boundaries. To theoretically investigate the magnetic properties of a crystal of ferromagnetic bcc iron, the wave functions of the iron atom calculated in view of the spin polarization of a core by the Hartree-Fock method with local exchange-correlation potentials have been used as base functions. This has made it possible to optimize the choice of a zero approximation for the description of the electronic states of ferromagnetic iron and to attain good agreement with the experimental values of the magnetic moment (A mu(theor) = 2.23A mu(B), A mu(exp) = 2.218A mu(B)), of the exchange splitting of the crystal term P-4 (Delta(theor) = Delta(exp) = 0.112 Ry), and of the cross-sections of the Fermi surface. A similar approach has been used to investigate the magnetic states of clusters (nanoclusters) based on the method of scattered waves. The approach developed for clusters of the alloy under investigation makes it possible to calculate the alloy magnetic properties in relation to the cluster size for a varied lattice parameter.

Аннотация: The crystal structure of Tb(30)Fe(70) and Co(50)Pd(50) nanocrystalline films with strong magnetic anisotropy perpendicular to the film plane (K(perpendicular to) similar to 10(6) erg/cm(3)) is investigated using electron diffraction and transmission electron microscopy. All the studied films in the initial nanocrystalline phase undergo an explosive crystallization with the formation of dendrite structures. It is demonstrated that, after crystallization, the Tb-Fe and Co-Pd films exhibit a tetrahedrally close-packed atomic structure that has no analogs among these materials in the equilibrium state. The internal stresses in the films under investigation are estimated from an analysis of the bend extinction contours in the electron microscope images. The inference is made that strong perpendicular magnetic anisotropy can be associated with magnetostriction anisotropy due to the specific features of the film structure.

Аннотация: The aim of the work is to elucidate the origin of magnetization presence in austenitic Fe86Mn13C steel after dynamic loading. The observation of microstructures in the region of transition from FCC austenitic Fe86Mn13C steel to FK12 + FK14 type of Frank-Kasper tetrahedral close packed structure is described. We used the methods of optical microscopy, electron microscopy, electron diffraction and X-ray-diffraction to investigate the phase transition region. Changes of local magnetization were estimated by induction method. To explain the magnetization origin of the sample consisting of austenite grains and intergranular layers, which have Frank-Kasper's structure (FK12 + FK14) typical of beta-Fe-Mn, the local electronic structure has been investigated for intergranular layers. The local electron structure of FK12 and FK14 clusters have been simulated by method of self-consistent field to understand the nature of non-zero magnetization of the Fe87Mn13 alloy exposed by shock deformation. It was shown, that numbers of states with upward and downward spins are not equal. Therefore the occurrence of magnetization is possible. (c) 2009 Published by Elsevier Ltd
