Conclusions

  1. 1.

    By calculating the level of dispersion hardening of alloys due to coherent nitrides in nitriding we can choose the most effective hardening nitride by two criteria, i.e., the minimum volume fraction of segregations and the minimum concentration of the alloying element.

  2. 2.

    From the standpoint of the maximum volume fraction of segregations in nitriding the most effective hardeners for Fe-, Co-, and Ni-matrices are hafnium and zirconium nitrides. With allowance for the requirement that the concentration of the alloying element be minimum, the maximum hardening effect is provided by titanium nitrides.
