Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    To obtain the necessary operating characteristics after facing of worn vanes from steam turbines, the heat treatment should consist of high-temperature tempering and induction hardening.

  2. 2.

    The best mechanical properties, meeting the requirements, are obtained by facing steel 15Kh11MF with steel 20Kh13 and tempering at 660°.
