Nanocarbides – Enhancing technological properties of tool steels by cryogenic treatment

Initial Position:

  • Cryogenic treatment – adjunctive treatment in hardening and tempering process to improve wear resistance and toughness of tool steels.
  • Large amount of individual studies with different results leads to a controversial discussion during the last years.
  • The actual metallurgical mechanisms in steels are not fully understood, and some existing hypotheses need to be verified.
  • Therefore, the potential of these technologies for tool users has not been exploited sufficiently.

Aims:

  • Determination of the optimal the cryogenic treatment including heat treatment process parameters for the selected steels.
  • Contribution to the understanding of the processes involved in cryogenic treatment and their effects on the properties of the treaded materials.

Results:

  • Introduction of the cryogenic treatment to the operational application for tool users.
