Conclusions

  1. 1.

    In a study of the formation of the structure of low-alloy manganese steel 09G2 and steel 12G2B with niobium we found that the austenite grain size and the difference in grain sizes decrease with lowering of the deformation temperature and with increasing deformation and increasing holding time (up to 30 sec) after deformation. These relationships hold true for steel 12G2B only with practically complete solution of the carbonitride phase (heating above 1280°).

  2. 2.

    With partial solution of the carbonitride phase (heating to 1200°) in low-alloy steel with niobium at a deformation temperature of 1000° and higher the austenite grain size and the difference in grain sizes decrease with increasing deformation and decreasing deformation temperature. At lower temperatures the austenite grain size is very small (grade 10–11, GOST 5639-65) and is independent of the deformation conditions.
