Conclusions

  1. 1.

    For some steels there is a specific cooling rate in the martensitic region at which the probability of quench cracks is maximum. A change in the cooling rate reduces the probability of crack formation.

     
  2. 2.

    During the transformation of austenite to martensite there is considerable evolution of heat, i.e., on the temperature curves there are horizontal sections that occur at lower temperatures with increasing cooling rates, these sections disappearing completely during rapid cooling.
