Conclusions

  1. 1.

    We developed a method of electrolytic separation of excess phases (M6C, AB2, and σ-phase) in Cr−Ni−Mo alloys KhN70M and KhN55M.

     
  2. 2.

    We found that silicon in the KhN70M alloy at the concentrations investigated favors precipitation of cubic carbides of the M6C type and a hexagonal phase of the AB2 type.

     

An increase of the silicon content from 0.06 to 1.5% widens the temperature range in which these phases exist (800–1100°C) and increases their quantity.
