Topological passivation makes high strength alloys insensitive to hydrogen embrittlement
Huijie Cheng, Binhan Sun, Aochen Zhang +6
Infrastructure parts for a hydrogen (H) economy need alloys that are mechanically strong and at the same time resistant to the most dangerous and abrupt type of failure mode, namel…
Protection of metal interfaces against hydrogen-assisted cracking
Guillaume Hachet, Shaolou Wei, Ali Tehranchi +8
Enabling a hydrogen economy requires the development of materials resistant to hydrogen embrittlement (HE). More than 100 years of research have led to several mechanisms and model…
Temperature and misorientation-dependent austenite nucleation at ferrite grain boundaries in a medium manganese steel: role of misorientation-dependent grain boundary segregation
Rama Srinivas Varanasi, Osamu Waseda, Faisal Waqar Syed +4
In the current work, we study the role of grain boundary (GB) misorientation-dependent segregation on austenite nucleation in a 50% cold rolled intercritically annealed 10Mn-0.05C-…
Segregation at prior austenite grain boundaries: the competition between boron and hydrogen
Guillaume Hachet, Ali Tehranchi, Hao Shi +8
The interaction between boron and hydrogen at grain boundaries has been investigated experimentally and numerically in boron-doped and boron-free martensitic steels using thermal d…
Optimizing site-specific specimen preparation for Atom Probe Tomography by using hydrogen for visualizing radiation-induced damage
Aparna Saksena, Binhan Sun, Xizhen Dong +3
Atom probe tomography (APT) is extensively used to measure the local chemistry of materials. Site-specific preparation via a focused ion beam (FIB) is routinely implemented to fabr…
Chemical heterogeneity enhances hydrogen resistance in high-strength steels
Binhan Sun, Wenjun Lu, Ran Ding +7
When H, the lightest, smallest and most abundant atom in the universe, makes its way into a high-strength alloy (>650 MPa), the material's load-bearing capacity is abruptly lost. T…
