Hydrogen-assisted decohesion and localized plasticity in dual-phase steel
Motomichi Koyama,Motomichi Koyama,Cemal Cem Tasan,Eiji Akiyama,Kaneaki Tsuzaki,Kaneaki Tsuzaki,Dierk Raabe +6 more
TL;DR: In this article, a high-resolution scanning electron microscopy-based damage quantification technique has been employed to identify strain regimes where damage nucleation and damage growth take place, both with and without hydrogen precharging.
Journal ArticleDOI
Effect of hydrogen on the fracture behavior of high strength steel during slow strain rate test
TL;DR: In this paper, the effect of hydrogen on the fracture behavior of quenched and tempered AISI 4135 steel at 1450 MPa was investigated by means of slow strain rate tests on smooth and circumferentially-notched round-bar specimens.
