Conclusions

  1. 1.

    For calculating the parameters of hardening of sintered steel and titanium it is expedient to use the tenets of the plasticity theory of porous bodies.

     
  2. 2.

    The hardening curve of the metallic base of a porous body does not, as a rule, coincide with the hardening curve of the cast metal with analogous chemical composition, and it depends but slightly on the initial relative density of the material.
