Reliable and efficient testing of materials under the influence of hydrogen using the hollow specimen method

The hollow specimen method is a promising method for investigating hydrogen embrittlement in metals, which is currently still in the standardization phase. Although the technique is highly relevant, many of the influencing factors have not yet been fully examined, and the method itself is not developed and standardized in its application. The goal is to systematically identify and evaluate these factors and testing conditions, laying the foundation for comparable and reproducible analysis as well as targeted standardization of the measurement method.
