Demagnetization curves and stress-strain compression curves of Fe-32Cr-22Co-(2X) (wt. %) hard magnetic alloys with highest level of magnetic properties. X = Mo, Nb, Si, Ti, V, W.

Microstructure formation during FSW under low heat input conditions is determined by processes of severe plastic deformation of ferritic and austenitic grains, followed by the transformation of deformed austenite into martensite. In the ferrite phase, the formation of a simple shear texture of the D1/D2 {112}<111> type was revealed.

Phase energy diagram showing the destabilization of TiC phase relative to carbon solid solution in titanium matrix under high pressure. The electron density distribution shows the overlap of electron clouds between titanium, which creates an octahedral complex with carbon, and the outer titanium atoms, which explains the increase in the energy of the system

Diagram showing links ‘90-deg domain types in the tetragonal phase – volume fraction v_R of the rhombohedral phase – difference of polarizations P_max – P_r‘ in BCZT–xGO. At max (P_max – P_r), the optimum volume fraction nT,opt of the 90-deg domains obeys the condition v_R ca.= 1 – n_T,opt.

Martensitic transformation during inter-gas atomization involves pronounced selection of crystallographic variants. Crystallographic preference of twin-related V1/V2 martensite variants was found.

Some regions of thin foil cut from plastically deformed copper were analysed by EBSD and TEM in order to clarify arrangement and density of dislocations.

The graphical annotation shows the characteristic structural features revealed due to corrosion in NaCl solution in copper samples in the as received state, after recrystallization and after structure optimization based on grain boundary engineering in two modes.

2D-film based on borophene and boron nanotube with adsorbed lithium atoms. The adsorption energy does not exceed the cohesion energy of lithium.

Asymmetric rolling at room temperature and subsequent low-temperature annealing allows the average grain size of the initial coarse-grained Grade 4 titanium to be reduced by two orders of magnitude. Asymmetric rolling, due to structural refinement, contributes to an increase in the yield and tensile strength by more than one and a half times.

The problem to diminish the thickness non-uniformity of spherical vessels manufactured by means of superplastic forming of an envelope consisting from two circular blanks welded along their periphery is considered by means of computer simulations.

Improving functional behavior of a novel Ti-18Zr-13Nb-2Sn shape memory alloy by thermomechanical treatment

Structure of FeGaTb powder, FeGaTb/epoxy resin composite and magnetostriction measurement of samples.

The saturation of the relief surface during plasma electrolyte processing occurs significantly unevenly.

The conception of irregular fullerene-based helical oligomers was introduced and their structure and polarizability were calculated with relevant DFT techniques. Their mean polarizabilities and distances between the terminal fullerene units are symbate. Helical oligomers show subadditivity of polarizability in contrast to the oligomers of other classes.
