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.

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.

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

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.

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.

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.

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

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.

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

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.

The figure shows regression analysis of the mass gain curves and the rate of mass gain depending on oxidation time obtained for samples of the TNM, TNZ and TNZ+ alloys in the near duplex (1 and 2) and near lamellar (3 and 4) conditions subjected to oxidation at 800°C.
