Conclusions

  1. 1.

    Due to a developed chemical inhomogeneity, ChVG has quite a wide intercritical temperature range Ac 1 s -Ac 1 f , which may be used, e.g., in heating for normalizing with the aim of increasing mechanical properties.

     
  2. 2.

    A ferrite-austenite structure is formed with heating in the intercritical temperature range, which makes it possible to obtain after air cooling of up to 750–780 MPa, δ up to 10–12%, anda up to 0.40–0.45 MJ/m2.

     
  3. 3.

    Cast iron ChVG may be recommended to replace cast iron forgings for the manufacture of engine components. The advantages of ChVG are simpler component production technology and higher mechanical properties.
