FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely to a method for obtaining technically pure nano-twinned titanium material. The method for obtaining technically pure nano-twinned titanium material involves casting of technically pure titanium material containing not more than 0.05 wt % N, not more than 0.08 wt % C, not more than 0.015 wt % H, not more than 0.50 wt % Fe, not more than 0.40 wt % O and the rest is not more than 0.40 wt %; cast material is brought to the temperature on the level of or below 0°C and plastic deformation is performed at this temperature in such a degree that nano-twins are formed in the material.
EFFECT: material is characterised by high strength and ductility characteristics.
