Metal Science and Heat Treatment Aims and scope

Conclusions

The overheated coarse-grained structure of high-alloy die steels can be refined as follows.

  1. a)

    For steels with supercooled austenite of low resistance in the pearlitic region (3Kh2V8F and 40Kh·5MF) by ensuring the pearlitic transformation during repeated annealing in the pearlitic transformation range.

  2. b)

    For steels with austenite of high resistance in the pearlitic region (27Kh2N2MVF type) by rapid heating to standard recrystallization temperatures, or long preliminary tempering at subcritical temperatures, or multiple recrystallization.
