Conclusions

  1. 1.

    The maximum damping in steel with 11% Cr corresponds to a content of 0.5–4% Al and it depends on a heat-treatment schedule. In particular, after annealing at 850°C a maximum is observed for steel 04Kh11Yu and it is δm=16%, which is much higher than for steel of the Kh13 type (δm≤5%). Steel with addition of 0.5–4% Al has high impact strength and satisfactory strength.

     
  2. 2.

    In order to achieve high damping and good treatment efficiency, particularly hot forming, steel type 04Kh11 should be alloyed with 0.5–3% Al.

     
  3. 3.

    Damping mechanisms for Cr−Al steel are of a magnetomechanical nature. In view of this, in constructing articles with this steel it is necessary to consider their stressed state and the effect of a magnetic field on damping.
