Hydrogen Visualization in Steels Using Ag Decoration Method

Prevention of Hydrogen Embrittlement in Steels

The essential facts about the nature of the hydrogen embrittlement of steels have now been known for 140 years. It is diffusible hydrogen that is harmful to the toughness of iron. It follows, therefore, that the harmful influence of diffusible hydrogen can be mitigated by preventing its entry into steel or by rendering it immobile once it penetrates the material. This review deals with the meth...

Hydrogen Induced Stress Corrosion of Prestressing Steels - Introducing a New Testing Method

The causes for the susceptibility of prestressing steels to hydrogen induced stress corrosion and the failure mechanisms occurring could be researched in depth. In contrast to this an exact testing method on the evidence of the prestressing steel sensitivity valid for all steel types does not exist. This has caused not only prejudices against prestressed buildings but has also led to additional...

Atomic-scale decoration for improving the pitting corrosion resistance of austenitic stainless steels

Stainless steels are susceptible to the localized pitting corrosion that leads to a huge loss to our society. Studies in the past decades confirmed that the pitting events generally originate from the local dissolution in MnS inclusions which are more or less ubiquitous in stainless steels. Although a recent study indicated that endogenous MnCr2O4 nano-octahedra within the MnS medium give rise ...
