In the present work, possibility of applying severe torsion deformation (STD) to a bulk near-equiatomic NiTi shape memory alloy in order accumulate super-high strain and improve mechanical functional properties was studied. STD performed using multidirectional test system “BÄHR MDS-830” at temperature 500 °C (the upper border for development dynamic polygonization) 14 30 turns with accumulated ...

This paper focuses on the processes of occurrence magnetization during structure formation in samples Ni51Ti49 alloy under deformation conditions. The possibility existence a phase with an FCC (face-centered cubic) lattice titanium nickelide has been demonstrated by electron microscopy and diffraction. It discovered that interplanar distances BCC110 (body-centered cubic), FCC111, HCP002 (hexago...

Increase in the operational functionality of space technology leads to necessity creating large-sized transformable systems. The development adequate models which are used computational experiments simulate opening structures is great importance. Significant progress has been made field antennas: ratio mass reflector its working area decreased 0.5–1.5 kg/m 2 . Despite significant achieved desig...

TiO(2)@carbon core/shell nanofibers (TiO(2)@C NFs) with different thinkness of carbon layers (from 2 to 8 nm) were fabricated by combining the electrospinning technique and hydrothermal method. The results showed that a uniform graphite carbon layer was formed around the electrospun TiO(2) nanofiber via C-O-Ti bonds. By adjusting the hydrothermal fabrication parameters, the thickness of carbon ...
