Conclusions

  1. 1.

    An examination is made of the behavior of a porous solid containing several dissolved gases. Equations describing the kinetics of pore size variation in various specific cases are proposed and analyzed.

  2. 2.

    It is shown that, with reactive gases, high total gas pressures may be generated in the pores of a solid even when these gases have only a small solubility in the solid.

  3. 3.

    To lower the gas pressure in the pores of a metal, it is necessary either to decrease the amount of gas dissolved in the metal or introduce alloying additions with which the gas will combine to form thermodynamically stable solid compounds.
