Fraunhofer IWM and the US institute NIST are jointly developing a prediction model for components. It is intended to help build the hydrogen economy.
Microautoclave test setup for mechanical in-situ testing of micro-samples in gaseous hydrogen. Quasi-static tensile tests and fatigue tests can be performed at hydrogen gas pressures of up to 5 MPa (50 bar).

The Fraunhofer Institute for Mechanics of Materials (IWM) and the US National Institute of Standards and Technology (NIST) have launched a research project aimed at significantly accelerating the qualification of components for hydrogen applications.
The “HyLife” project is developing a physics-based prediction model for the service life of materials in contact with hydrogen. The goal is to shorten the previously time-consuming testing procedures and also to increase the safety of hydrogen infrastructures.
Precise Predictions
The researchers are relying on micro-sampling techniques and high-throughput fatigue testing to accurately predict damage to materials. The model is to be incorporated into international standards such as ASME B31.12 and ISO 11114-4 in the future, thereby accelerating the development of the hydrogen economy.
The project addresses a key challenge facing the industry: hydrogen can alter the microstructure of steels and lead to cracking. Current testing methods are time-consuming and expensive, which delays the introduction of new materials.
