Conclusions

  1. 1.

    Analysis of the crystallographic texture of the α-phase in rolled sheets of titanium pseudo-α-alloys that had previously been subjected to short-term annealing at different temperatures makes it possible to determine the temperature of the polymorphic transformation of these alloys with high accuracy and investigate the recrystallization process of the high-temperature phase. The temperature Tpt=955±15 and 1018±17°C for alloys OT4 and VT20, respectively.

     
  2. 2.

    Use of x-ray photography with layer-by-layer removal of material from the surface of the specimen makes it possible to ascertain the variation in the temperature of the phase transition over a section of an article in the presence of an impurity gradient across the thickness. Thus, Tpt=1053±17°C on the surface of an alloy VT20 sheet; this is ∼35°C higher than that in the core.
