Web28 feb. 2024 · There are several concepts to explain how hydrogen leads to the failure of steels and alloys. However, the loss of ductility due to hydrogen remains a serious problem for the design and fabrication of high-strength steels. For some steels, their well-balanced strength and ductility are achieved by a transformation-induced plasticity effect (TRIP). Web20 dec. 2024 · Hydrogen-induced cracking (HIC) is also known as: Cold cracking, because it occurs when the metal has cooled below 150°C. Delayed cracking, because its formation is sometimes delayed for 20 hours or more, Underbead cracking, because in most cases it is located at the HAZ underneath the weld bead. Hydrogen Embrittlement.
