Conclusions

  1. 1.

    The structure of quenched steel determines the character and kinetics of the carbide reaction during subsequent tempering.

     
  2. 2.

    In the presence of polygonized martensite the mechanical properties of the steel reach fairly high levels: σb = 65−70 kgf/mm3,a0.25 at −40°=5.0 kgf-m/cm2.

     
  3. 3.

    Diffusional transformations during tempering are less active in quenched steel 16GFR than 16G2.

     
  4. 4.

    The effect of the carbon content on the properties after tempering of quenched steel 16GFR levels out due to compensation in the process of the carbide reaction.
