Conclusions

  1. 1.

    We have analyzed the possibility of applying metallographic inspection to solids with defects which have been subjected to high-temperature annealing for the accurate determination of the densities of such solids (microscopic pycnometry).

     
  2. 2.

    As an example, we have considered the problems concerning the defects appearing in metals which have been subjected to cyclic heat-treatment and in metals obtained by electrolytic deposition.

     
  3. 3.

    The energy of vacancy formation in copper was determined with respect to data on the actual density of copper which was subjected to cyclic heat treatment.
