Conclusions

  1. 1.

    The highly etched areas of forgings annealed under the conditions shown in Fig. 1 are due to the formation of a mixed microstructure of pearlite and intermediate decomposition products of austenite (troostite, bainite).

     
  2. 2.

    This defect can be corrected by repeated annealing under conditions shown in Fig. 4a.

     
  3. 3.

    Newly manufactured forgings should be annealed under conditions shown in Fig. 4b to prevent the formation of intermediate decomposition products.
