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 permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in … Meer weergeven Hydrogen embrittlement is a complex process involving a number of distinct contributing micro-mechanisms, not all of which need to be present. The mechanisms include the formation of brittle Meer weergeven While most failures in practice have been through fast failure, there is experimental evidence that hydrogen also affects the fatigue properties of steels. This is entirely expected given the nature of the embrittlement mechanisms proposed for fast fracture. … Meer weergeven During manufacture, hydrogen can be dissolved into the component by processes such as phosphating, pickling, electroplating Meer weergeven Most analytical methods for hydrogen embrittlement involve evaluating the effects of (1) internal hydrogen from production … Meer weergeven Hydrogen embrittles a variety of metals including steel, aluminium (at high temperatures only ), and titanium.
