An overview of additive manufacturing techniques in Ukraine from the end of the last century to 2021 is presented. The current state of 3D printing in Ukraine was analyzed in terms of new developments (startups), research areas, and direct implementation of additive manufacturing techniques. The main scientific and research teams that were actively...

The microstructure, phase composition, and mechanical properties of Ti–Cr–Al–Si–O alloys in ascast state and after annealing at 800°C have been studied. The as-cast alloys with 50 and 60 at.% Ti have two phases: a 1/1 α(TiCrSi) cubic approximant of the quasicrystalline phase and an intermetallic Cr2Ti(C14) Laves phase in different ratios. The as-ca...

SiC reinforced Al–Mg–Si powders were ball-milled in a mixer device with different milling times. This process was performed to observe the possible effects of different milling times on the final microstructure and properties of the materials. Mechanically alloyed powder mixtures were sintered to produce a billet in protective gas atmosphere (argon...

The effect of TiB2 and CrB2 additives on the oxidation behavior of composites made of the NiCrBSiC and FeNiCrBSiC self-fluxing alloys has been studied in air at temperatures to 800°C. It is found that the FeNiCrBSiC–20 wt.% TiB2 composite is oxidized most intensively. Oxidation occurs selectively: titanium diboride is oxidized at 450–550°C to form ...

A fragment of the Al corner in the ternary Al–Ge–Mg phase diagram has been constructed. Experimental methods have shown that the tie-line of the L ⇆ α-Al + Mg2Ge three-phase eutectic equilibrium (corresponding to the maximum temperature of eutectic transformation) does not match the stoichiometric Al–Mg2Ge section in the ternary Al–Ge–Mg phase diag...

Total ionic, grain and grain boundary conductivity of traditional 8YSZ and promising 10Sc1CeSZ electrolytes for solid oxide fuel cells (SOFC) were studied. Samples were sintered at 1400°C due to best values of the ionic conductivity, as it was shown earlier. The total conductivity of 10Sc1CeSZ electrolytes at 600°C varied from 0.019 to 0.046 S/cm d...

The laboratory technique for producing a precipitation-hardened Ni20Cr6Al–1Y2O3 powder alloy has been described and the rolling process for making sheets 0.5 to 0.05 mm thick has been developed to determine the functional characteristics and fabricate a thermal-barrier structure. Brazing has been employed to produce a prototype complex metallic the...

Ribbons with a porosity varying from 22 to 0.5% have been produced by rolling a multilayer knitted-mesh package made of 12Kh18N10T steel wire bundles 30 μm in diameter. Experimental and generalized analytical dependences of fatigue characteristics and their combinations on the porosity and rolling strain have been established using resonant cyclic ...
