Conclusions

  1. 1.

    Calcium modification of cast iron causes a decrease in the stability of cementite in annealing.

  2. 2.

    In the calcium-modified iron significant graphitization occurs in heating of it to 700°C with a hold of not less than 4 h.

  3. 3.

    For decomposition of cementite in calcium-modified iron in heating of it to 800°C a hold of 3 h and more is necessary. With an increase in heating temperature the hold must be reduced.
