Conclusions

  1. 1.

    The fine structure is the determining factor in the formation of the physicomechanical properties of steel 06Kh14N6D2MBT in all stages of aging and overaging at temperatures of 100–550°.

     
  2. 2.

    The ductile-brittle transition temperature Tcr determined atap=3 kgf-m/cm2 is far lower (−80°) for steel 06Kh14N6D2MBT than for pearlitic steel 12Kh2NMFA, both steels having the same fracture toughness at standard temperature.

     
  3. 3.

    Intensive softening of steel 06Kh14N6D2MBT begins after heating above 450°, i.e., when the overaged condition is reached.
