Dispersion hardening of high-strength Ni−Co−Mo steels

  • Published:
Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    Secondary hardening in tempering of carbon-containing iron-nickel martensite alloyed with molybdenum is caused by precipitation of metastable molybdenum carbide, which occurs with greater completeness and, in addition, on a background of the process of Fe−Co type close-range ordering in steels additionally containing cobalt.

  2. 2.

    As the result of use of the secondary hardening effect it is possible to obtain a high combination of mechanical properties in carbon-containing iron-nickel martensite-base steels alloyed with cobalt and molybdenum.
