Reasons for the high impact strength of steel containing rare earth metals

  • Published:
Metal Science and Heat Treatment Aims and scope

Summary

  1. 1.

    We found that the inclusions along the boundaries have different shapes in rolled 40KhNMA steel with and without ferrocerium. Probably this is one of the reasons for the difference is the impact strength of samples in the transverse direction.

  2. 2.

    We showed that the rare earth metals do not prevent inclusions along the grain boundaries.
