Understanding the mechanisms behind hydrogen embrittlement in high-strength steel (IMAGE)
Caption
Exposure to hydrogen negatively affects the mechanical properties of high-strength steel, limiting its use in the hydrogen automobile industry. Through a series of experiments involving novel mechanical tests, scanning electron microscopy, and thermal desorption spectroscopy, scientists managed to shed light on the types of defects that form at the crystalline lattice right below the surface of cracks caused by hydrogen.
