How Does Hydrogen Affect the Mechanical Behavior of Metals and Alloys?

María Jazmin Duarte Correa

It has long been understood that hydrogen has a negative effect on metals like iron and steel. Studying this phenomenon is not easy because of the fact that hydrogen is everywhere, is extremely small and is in constant motion. In this video, MARÍA JAZMIN DUARTE CORREA explains how new technologies can help to pin down the impact of hydrogen in this context. Focusing on the particular challenges involved in studying diffusible hydrogen, Duarte explains how nano indentation can be used to specifically identify its effects. Looking forward, the research seeks to support the development of materials that are resistant to deformation caused by hydrogen. This has particular relevance for the energy sector where the storage and transportation of hydrogen presents a pressing challenge.

Max-Planck-Institut für Eisenforschung

Novel alloys for automotive lightweight design and airplane turbines, materials for sustainable energy conversion and storage, and the development of big data and machine learning methods – these are just a few examples of the research areas that are being investigated by the scientists of the Max-Planck-Institut für Eisenforschung. The team of engineers, material scientists, physicists, and chemists develops tailored materials and methods for mobility, energy, infrastructure, and information. To this end, the researchers study complex materials with atomic precision under real environmental conditions.
