Metals can be exposed to hydrogen from two types of sources: gaseous hydrogen and hydrogen chemically generated at the metal surface. Gaseous hydrogen is molecular hydrogen and does not cause embrittlement though it can cause hot hydrogen attack (see below). See more Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can See more Hydrogen embrittles a variety of metals including steel, aluminium (at high temperatures only ), and titanium. Austempered iron is also susceptible, though austempered steel (and possibly other austempered metals) displays increased … See more Hydrogen embrittlement is a volume effect: it affects the volume of the material. Environmental embrittlement is a surface effect where … See more Hydrogen embrittlement can be prevented through several methods, all of which are centered on minimizing contact between the metal and hydrogen, particularly during fabrication and the electrolysis of water. Embrittling procedures such as acid pickling should … See more Hydrogen embrittlement is a complex process involving a number of distinct contributing micro-mechanisms, not all of which need to be present.
