Conclusions

  1. 1.

    External stress applied to a specimen during the bainitic transformation causes significant acceleration of this process and a reduction in its incubation period. An axial 〈110〉α texture forms when the transformation takes place under tensile stress.

     
  2. 2.

    Preliminary thermal deformation of austenite in the region of its maximum stability (or a developed dislocation structure) gives rise to braking of the bainitic transformation. During the transformation of austenite deformed by rolling, its texture is transformed into a {112}〈110〉α texture.

     
  3. 3.

    An external stress that acts during the transformation of deformed austenite places additional constraints on the process of the γ→α lattice reconstruction. Those bainite crystals, during whose formation shear occurs along the planes with the maximum tangential stresses, receive preference.

     
  4. 4.

    A {112}〈uvw〉α texture, which contributes to an increase in property isotropy in the plane of rolling, is formed LTMIST with transformation under tensile stress parallel to the direction of rolling.
