Effect of fracture mode on acoustic emission behavior in the hydrogen embrittled low-alloy steel

Merson, ED; Myagkikh, PN; Klevtsov, GV; Merson, Dmitry L.; Vinogradov, Alexey (Journal article; Peer reviewed, 2018)

Hydrogen embrittlement (HE) of steels and other alloys is a long-standing scientific and engineering problem causing sudden premature failures of industrial components. Although several mechanisms of hydrogen-assisted ...
Probing elementary dislocation mechanisms of local plastic deformation by the advanced acoustic emission technique

Vinogradov, Alexey; Danyuk, Alexei V.; Merson, Dmitry L.; Yasnikov, Igor S. (Journal article; Peer reviewed, 2018)

To gain a deeper insight into fundamental processes of localised plastic deformation, we propose a new strategy for micro-mechanical testing combining the micro-scale scratching and analysis of low amplitude acoustic ...
