Towards establishing best practice in the analysis of hydrogen and deuterium by atom probe tomography
Baptiste Gault, Aparna Saksena, Xavier Sauvage +42
As hydrogen is touted as a key player in the decarbonization of modern society, it is critical to enable quantitative H analysis at high spatial resolution, if possible at the atom…
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…
A new class of carbon stabilized austenitic steels resistant to hydrogen embrittlement
Heena Khanchandani, Stefan Zeiler, Lucas Strobel +2
High strength steels are susceptible to H-induced failure, which is typically caused by the presence of diffusible H in the microstructure. The diffusivity of H in austenitic steel…
Atomic scale understanding of the role of hydrogen and oxygen segregation in the embrittlement of grain boundaries in a twinning induced plasticity steel
Heena Khanchandani, Baptiste Gault
Twinning induced plasticity (TWIP) steels are high strength metallic materials with potential for structural components in e.g. automotive applications. However, they are prone to…
Transmission Kikuchi diffraction mapping induces structural damage in atom probe specimens
Baptiste Gault, Heena Khanchandani, T. S. Prithiv +2
Measuring local chemistry of specific crystallographic features by atom probe tomography (APT) is facilitated by using transmission Kikuchi diffraction (TKD) to help position them…
Hydrogen embrittlement of twinning-induced plasticity steels: contribution of segregation to twin boundaries
Heena Khanchandani, Rolf Rolli, Hans-Christian Schneider +2
Metallic materials, especially steel, underpin transportation technologies. High-manganese twinning induced plasticity (TWIP) austenitic steels exhibit exceptional strength and duc…
Hydrogen-induced hardening of a high-manganese twinning induced plasticity steel
Heena Khanchandani, Dirk Ponge, Stefan Zaefferer +1
High-manganese twinning-induced plasticity (TWIP) steels exhibit high strain hardening, high tensile strength, and high ductility, which make them attractive for structural applica…
Laser-equipped gas reaction chamber for probing environmentally sensitive materials at near atomic scale
Heena Khanchandani, Ayman A. El-Zoka, Se-Ho Kim +6
Numerous metallurgical and materials science applications depend on quantitative atomic-scale characterizations of environmentally-sensitive materials and their transient states. S…
