FIELD: metallurgy.
SUBSTANCE: load carrying components are made of VT8 titanium alloy. Then heat treatment is sequentially performed in three stages. The first is carried out at temperature from 600 to 650 °C, at which the titanium silicides are released from supersaturated solid solutions -α and -phases β. The second is carried out at temperature from 850 °C and above, which is characterized by conversion of the phase composition from α- to β-. The third is conducted at temperature from 950 to1100 °C. At 1100 °C the phase composition of the alloy is represented only by β-phase.
EFFECT: improved strength characteristics of VT8 titanium alloy parts.
