    The mechanical behavior of the VT20-hydrogen system was investigated experimentally in the temperature range 823-1073 K at deformation rates of 0.0001-1/s. It is shown that the alloying of VT20 by 0.4-0.58 percent hydrogen reduces the deformation resistance of the alloy by a factor of 1.5-2 at all deformation stages. The effect is particularly pronounced at lower deformation rates. The possible mechanisms controlling the plastic deformation of the alloy are examined. 22 refs.

    A possibility of titanium and nickel-based alloys composite materials formation using combination of explosive welding and spark plasma sintering technologies was demonstrated in the current research. An employment of interlayer consisting of copper and tantalum thin plates makes possible to eliminate a contact between metallurgical incompatible titanium and nickel that are susceptible to intermetallic compounds formation during their interaction. By the following spark plasma sintering process the bonding has been received between titanium and titanium alloy VT20 through the thin powder layer of pure titanium that is distinguished by low defectiveness and fine dispersive structure.
