Parts: I. Corrosion of Metals. 1. Nucleation and development of pitting corrosion in iron and steel (Z. Szklarska-Śmialowska). 2. Stress corrosion cracking of structural steels in nitrate solutions (J. Flis). 3. Corrosion of structural materials in metal-cooled nuclear reactors (E. Hajewska). 4. Corrosion in molten salts - A thermodynamic approach (L. Suski). 5. Rotating disc in the transport of reactants during corrosion of copper, iron, and zinc with hydrogen and oxygen depolarization (Z. Zembura). 6. Displacement as a particular case of corrosion (J. Sedzimir). II. Interaction of Hydrogen with Metals and their Resultant Deterioration. 7. Effects of the interaction of hydrogen from the gas phase with the surface of transition metals (W. Palczewska, A. Frackiewicz). 8. Electrochemical aspects of hydrogen entry into iron and steel from aqueous solutions (T. Zakroczymski). 9. Dissolution and diffusion of hydrogen in iron and steel (W. Raczýnski). 10. Effect of hydrogen on mechanical properties and dislocation structure of iron and steel (E. Łunarska-Borowiecka, A. Zieliński). 11. Change in the real structure of nickel due to the Ni-&bgr; NiH phase transformation (A. Janko, J. Pielaszek). 12. Ionization of hydrogen on the surface of metals in aqueous solutions of electrolytes (A. Sadkowski et al.). 13. Effect of the oxide and sulphide inclusions on the absorption and permeation of hydrogen in steel (J. Foryst). Index.
