Hydrogen Embrittlement

Mechanical testing in a high pressure hydrogen is the most versatile HE testing method.

The electrochemical hydrogen permeation technique was introduced by Devanathan and Stachurski in 1962.

When performing SCC or HE tests, the tensile specimen is conventionally a solid piece of metal surrounded by the corrosive environment.

Conventionally, the hydrogen environment tests have been performed in water with dissolved hydrogen.

An electromechanical loading device can be integrated with a pressure vessel. Applications are related to the power generation construction material and off-
