Understanding and mitigating hydrogen embrittlement of steels ifi 142 1997 hydrogen embrittlement risk

Hydrogen embrittlement is a complex phenomenon, involving several length- and timescales, that affects a large class of metals. It can significantly reduce the ductility and load-bearing capacity and cause cracking and catastrophic brittle failures at stresses below the yield stress of susceptible materials. Despite a large research effort in attempting to understand the mechanisms of failure ifi 142 1997 hydrogen embrittlement risk USCAR5: Avoidance of Hydrogen Embrittlement of Steel - SAE ifi 142 1997 hydrogen embrittlement risk Hydrogen embrittlement of steel, which can cause brittle fractures under stress, occurs as a result of the absorption of hydrogen during cleaning, phosphate coating and plating processes. The susceptibility to hydrogen embrittlement increases with increasing stress (internal or externally applied stress) and increasing material strength. Stress corrosion cracking (SCC) of austenitic stainless and ifi 142 1997 hydrogen embrittlement risk Hydrogen embrittlement. This is the classic embrittlement process in which hydrogen atoms reduce the bond strength between atoms and cause loss of load bearing ability of the materials and also reduced ductility. The premature failure by hydrogen embrittlement is a function of applied stress and time. Hydrogen embrittlement in industries

Baking of fasteners to relieve hydrogen embrittlement The processed specimens are returned to the lab for the hydrogen embrittlement testing. IFI-142, Hydrogen Embrittlement Risk Management (available from Industrial Fasteners Institute, www.industrial-fasteners.org) gives detailed information on minimizing hydrogen pick-up during processing.
