Hydrogen embrittlement

Hydrogen embrittlement is a phenomenon in materials science that can occur in particular with certain metals. This effect occurs when hydrogen penetrates the metallic material and negatively influences the material properties. Hydrogen embrittlement can lead to a reduction in the ductility and strength of the material, which in turn leads to increased susceptibility to fracture.

Metals that are susceptible to hydrogen embrittlement show these weakening effects especially in environments where hydrogen is present. This can occur, for example, in industrial processes, chemical plants or in the processing of metals using hydrogen.

The mechanisms underlying hydrogen embrittlement are complex and depend on factors such as material type, stress state and environmental conditions. Hydrogen can penetrate into the metallic crystal lattice, diffuse there and lead to an impairment of the bonding forces.

Various measures are required to minimize hydrogen embrittlement, such as avoiding hydrogen contact, using less susceptible materials or applying protective coatings. Researching and understanding hydrogen embrittlement is of great importance to ensure that materials can be used safely and reliably in environments with hydrogen.
