Conclusions

  1. 1.

    The optimal combination of mechanical properties and damping capacity of structural steels of elevated and high strength can be obtained by quenching from 880° and tempering at 650° For carbon steel VSt 3 sp this heat treatment is useless — the damping capacity after heat treatment is the same as in the original condition.

     
  2. 2.

    The damping capacity after quenching+tempering at 650° is highest for steel 15KhG2SFR, followed by steels 14KhGS and 15KhG2SFMR, while the remaining steels have almost identical damping capacities. For structures subject to vibrations and dynamic loads we recommend the use of steels with a high damping capacity.

     
  3. 3.

    The damping capacity of the structural steels investigated consists of two components — damping due to the magnetic nature of the material and damping of nonmagnetic origin. The damping capacity is affected mainly (about 90%) by magnetomechanical phenomena.
