Conclusions

  1. 1.

    With phase transformation accompanied by an increase in volume, two plastic zones may occur in a plate — compression in the layer and tension in the core.

     
  2. 2.

    The absolute value of stresses due to phase transformation depends on the difference in the specific volumes of the phases and the ratio fo their mechanicla properties.

     
  3. 3.

    The equations obtained with regard to phase transformations during quenching indicate that the stresses resulting from phase transformation are tensile stresses on the surface of plates of steels with high hardenability. In plates of steels with low hardenability the entire quenched layer is under the influence of compressive stresses, which reach their maximum values at the inner boundary of the layer.
