Hydrogen embrittlement and corrosion behaviors in metals

The interface between a metal and its oxide or other corrosion films is a zone of great interest in the general phenomena of protection of metals. The system of iron and its oxides is considered in this work. Experiments are made using the electron diffraction high temperature camera on the oxidation of single crystals of iron. Definite orientation effects are found between the metal and the oxide if the oxidation is carried out slowly, for example, in a 50 per cent ‐50 per cent mixture at 750°C or in high vacuum. Rapid oxidation shows that the original orientation effects are not carried through to thick films.
