✦ Synopsis

There are three types of hydrogen embrittlement: a) hydrogen-reaction embrittlement, b) internal-hydrogen embrittlement, and c) hydrogenenvironment embrittlement.

This distinction was emphasized by Chandler and Walter [i]. The first two of these have been extensively studied in the past. The term hydrogen-environment embrittlement is used to signify the degradation of mechanical properties of a metal, which occurs while the metal is exposed to a hydrogen-environment.

Hydrogenenvironment embrittlement has been much less extensively investigated than hydrogen-reaction embrittlement or internal-hydrogen embrittlement. In particular the plastic behaviour associated with cyclic strain in high-pressure hydrogen is neither well documented nor well understood. This report gives the recent results of investigations of the effect of hydrogen at high pressures on the low-cycle endurance of steel. This work is one of a series covering a study of the resistance of metals to repeated loading in plastic ranges.
