Hydrogen Stress Cracking

Hydrogen Stress Cracking

Definition(s)

Hydrogen Stress Cracking

Cracking that results from the presence of hydrogen in a metal and tensile stress (residual and/or applied) NOTE HSC describes cracking in metals that are not sensitive to SSC but which can be embrittled by hydrogen when galvanically coupled, as the cathode, to another metal that is corroding actively as an anode. The term “galvanically induced HSC” has been used for this mechanism of cracking.

Hydrogen-induced cracking

Hydrogen-induced cracking

Definition(s)

Hydrogen-induced cracking

Planar cracking that occurs in carbon and low alloy steels when atomic hydrogen diffuses into the steel and then combines to form molecular hydrogen at trap sites. NOTE Cracking results from the pressurization of trap sites by hydrogen. No externally applied stress is needed for the formation of hydrogen-induced cracks. Trap sites capable of causing HIC are commonly found in steels with high impurity levels that have a high density of planar inclusions and/or regions of anomalous microstructure (e.g. banding) produced by segregation of impurity and alloying elements in the steel. This form of hydrogen-induced cracking is not related to welding.

Human-Centred Design (HCD)

Definition(s)

Human-Centred Design (HCD)

An approach to system design and development that aims to make interactive systems more usable by focussing on the use of the system; applying human factors, ergonomics and usability knowledge and techniques. Note: The term "human-centred design" is used rather than "user-centred design" in order to emphasize that this process also addresses impacts on a number of stakeholders, not just those typically considered as users. However, in practice, these terms are often used synonymously. Usable systems can provide a number of benefits including improved productivity, reduction in training needs, enhanced user well-being, avoidance of stress, increased accessibility, and reduced risk of harm.
