Conclusions

  1. 1.

    Microalloying with boron tends to increase the volume percentage of the quasi-eutectoid in the structure of annealed hypoeutectoid steels as a result of suppression of segregation of structurally free cementite on the intergrain boundaries.

  2. 2.

    The introduction of ∼0.003% of B to annealed low- and medium-carbon steels is equivalent to their being alloyed with 1–1.5% of Mn or Cr in terms of influence on structure formation.

  3. 3.

    Microalloying with boron contributes to the formation of a bainitic component in the structure of medium-carbon steels in the normalized state.
