Crack arrest markings in stress corrosion cracking of 7xxx aluminium alloys: insights into active hydrogen embrittlement mechanisms
Martí López Freixes, Xuyang Zhou, Raquel Aymerich-Armengol +4
Crack growth in stress corrosion cracking (SCC) in 7xxx Al alloys is an intermittent process, which generates successive crack arrest markings (CAMs) visible on the fracture surfac…
The Premartensite and Martensite in Fe50Rh50 System
Esmaeil Adabifiroozjaei, Fernando Maccari, Lukas Schaefer +19
Metallic/intermetalic materials with BCC structures hold an intrinsic instability due to phonon softening along [110] dirrection, causing BCC to lower-symmetry phases transformatio…
Nanoscale perspective on the stress-corrosion cracking behavior of a peak-aged 7XXX-Al alloy
Martí López Freixes, Lionel Peguet, Timothy Warner +1
High strength 7xxx Al-alloys are currently commonly used in aerospace and are expected to be increasingly employed in the automotive sector for weight reduction purposes. These all…
B dopant evolution in Pd catalysts after H evolution/oxidation reaction in alkaline environment
Se-Ho Kim, Su-Hyun Yoo, Leonardo Shoji Aota +4
Introduction of interstitial dopants has opened a new pathway to optimize nanoparticle catalytic activity for, e.g., hydrogen evolution/oxidation and other reactions. Here, we disc…
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…
Tailoring negative pressure by crystal defects: Crack induced hydride formation in Al alloys
A. Tehranchi, P. Chakraborty, M. L. Freixes +4
Climate change motivates the search for non-carbon-emitting energy generation and storage solutions. Metal hydrides show promising characteristics for this purpose. They can be fur…
Atomic scale evolution of the surface chemistry in Li[Ni,Mn,Co]O2 cathode for Li-ion batteries stored in air
Mahander P. Singh, Se-Ho Kim, Xuyang Zhou +6
Layered LiMO2 (M = Ni, Co, Mn, and Al mixture) cathode materials used for Li-ion batteries are reputed to be highly reactive through their surface, where the chemistry changes rapi…
The role of \b{eta} pockets resulting from Fe impurities in hydride formation in titanium
Qing Tan, Zhiran Yan, Huijun Wang +3
The corrosion potential of commercially pure titanium in NaCl solutions is dramatically affected by trace Fe additions, which cause the appearance of submicron pockets of \b{eta} p…
Atom probe analysis of battery materials: challenges and ways forward
Se-Ho Kim, Stoichko Antonov, Xuyang Zhou +6
The worldwide developments of electric vehicles, as well as large-scale or grid-scale energy storage to compensate the intermittent nature of renewable energy generation has genera…
Aluminum depletion induced by complex co-segregation of carbon and boron in a Σ 5 [3 1 0] bcc-iron grain boundary
Ali Ahmadian, Daniel Scheiber, Xuyang Zhou +4
The local variation of grain boundary atomic structure and chemistry caused by segregation of impurities influences the macroscopic properties of poylcrystalline materials. Here, t…
