Conclusions 1 The obtained strength and plasticity characteristics of titanium alloys VT1, OT4, VT6, and VT14 were at a linear stressed state in conditions of static and dynamic actions of forces. 2 Comparison of deformation resistance of the mentioned alloys at various deformation rates shows, that in theoretical calculations values sigma sub b st in a temperature range of hot pressure treatment 700-1000C can be used. 3 The ultimate strength sigma sub b sub D, obtained at dynamic elongation in the very same temperature range, is situated above the actual and calculated deformation resistances, which is explained by more considerable rates of deformation during dynamic elongation. 4 Plastic properties of alloys VT1, OT4, VT6, and VT14 relative elongation and narrowing of the transverse section decrease with an increase in rate of deformation.
