Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    Secondary hardening in 1Kh12N2VMF steel occurs as the result of the formation of the metastable carbide M2C enriched in chromium. This carbide has a hexagonal structure.

  2. 2.

    The maximum relaxation resistance of this steel at 300 and 350°C occurs after tempering at 450 and 500°C. Tempering ensures only a slight impoverishment of the solid solution in alloyed elements and the precipitation of the strengthening dispersed particles of the M2C carbide.

  3. 3.

    1Kh12N2VMF steel has a high resistance to relaxation at temperatures up to 350°C.
