Hydrogen embrittlement and delayed fracture of advanced multiphase high-strength steels

Obiettivo

Hydrogen embrittlement (HE) of multiphase high-strength steels is investigated. The aim is to gain fundamental understanding of the relation between the strength, microstructure, hydrogen solubility and diffusion and the mechanisms of HE.

Furthermore, the influence of the application environment is studied by carrying out mechanical testing at different loading conditions (strain rate, temperature, deformation path, etc.). In order to study the strain localisation and crack formation mechanisms related to HE, in-situ EBSD analysis will be performed in FESEM during plastic deformation. Based on the results, guidelines to avoid HE will be composed for steel manufacturers and end-users.
