Conclusions

  1. 1.

    A vibrofluidized bed can be used for quenching and the results are very similar to those from quenching in oil.

  2. 2.

    The cooling rate in a vibrofluidized bed decreases with the surface temperature of the piece; the highest cooling rate occurs in cooling the piece from 800 to 500°C. The cooling rate of a copper ball in this temperature range is higher in a vibrofluidized bed than in oil.
