Conclusions

  1. 1.

    With increasing tempering temperature (in the range of 620–680°C) the strength characteristics decrease monotonically, while the toughness (aC, T50) reaches a peak with tempering at 640°C.

     
  2. 2.

    With quenching from the intercritical temperature range the toughness does not reach a maximum value in the presence of more than 5% ferrite.
