It is determined that at the temperatures fall to the negative and cryogenic the titanium alloys strength naturally rises but the alongation, relative reduction and impact strength decreases in the indicating succession. The dynamics of amplification at the alloys cooling to the negative and cryogenic temperatures depends on alloying level The more alloying the less amplification during the cooling. A division of the titanium alloys in three groups according to the amplification at the temperature decreases is proposes. In spite of the decrease of plasticity characteristics and impact strength their absolutly value not decreases below the level of the proposed demands. It should be presented to the alloys VT6S and VT5-1 to their use in the negative and cryogenic temperatures.
