Fundamentals of Hydrogen Embrittlement
With 132 participants from industry and research, the event demonstrated how relevant the topic has become in the context of the energy transition. Hydrogen offers a wide range of opportunities, but at the same time poses demanding challenges for metallic materials that require a deep understanding of the underlying mechanisms. 

At the beginning of the webinar, the basics of hydrogen embrittlement were explained. Dr.-Ing. Jürgensen showed how hydrogen changes the mechanical properties of metallic materials, what failure mechanisms can occur, and why even ductile-appearing materials suddenly tend to fracture without deformation. This overview provided a solid basis for the subsequent in-depth content. 

Overview of Testing and Analysis Methods
A central focus was on testing and analysis methods. Participants gained insights into established and newer measurement methods that enable the detection and quantification of hydrogen. Particularly helpful was the classification of which method is suitable for which issue and how the results can be incorporated into safety-related decisions. 

Material Selection and Alloying Strategies
Material selection was also discussed in detail. Modern research results showed how materials can be specifically selected for use in hydrogen-containing environments and which alloying strategies are currently promising. For companies, this knowledge provides an important basis for designing components to be reliable in the long term and avoiding unexpected damage. 

Safety and Risk Minimization
In addition, safety-related aspects and strategies for risk minimization were presented. Participants were given clear guidelines on how to increase the reliability of components – from material selection and component design to testing and maintenance concepts. 

Current Developments and Discussion
Finally, Dr.-Ing. Jürgensen gave an overview of current developments in research and technology. New findings from modeling, characterization, and practical applications showed how dynamically the field is currently evolving. 

The subsequent discussion underscored the high level of interest among the expert community. Many questions related to specific application scenarios, industrial challenges, and the transferability of laboratory results to practical operation. 

With this webinar, the DGM offered an informative and practice-oriented event that presented fundamental concepts in an understandable way while also providing an in-depth look at current lines of research and safety-related issues.
