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…
Tailoring the plasticity of topologically close-packed phases via the crystals' fundamental building blocks
Wei Luo, Zhuocheng Xie, Siyuan Zhang +10
Brittle topologically close-packed precipitates form in many advanced alloys. Due to their complex structures little is known about their plasticity. Here, we present a strategy to…
Constructing phase diagrams for defects by correlated atomic-scale characterization
Xuyang Zhou, Prince Mathews, Benjamin Berkels +10
Phase transformations and crystallographic defects are two essential tools to drive innovations in materials. Bulk materials design via tuning chemical compositions has been system…
Atom probe analysis of BaTiO3 enabled by metallic shielding
Se-Ho Kim, Kihyun Shin, Xuyang Zhou +6
Atom probe tomography has been raising in prominence as a microscopy and microanalysis technique to gain sub-nanoscale information from technologically-relevant materials. However,…
Atomic motifs govern the decoration of grain boundaries by interstitial solutes
Xuyang Zhou, Ali Ahmadian, Baptiste Gault +4
Grain boundaries, the two-dimensional (2D) defects between differently oriented crystals, control mechanical and transport properties of materials. Our fundamental understanding of…
Chemical Partitioning at Crystalline Defects in PtAu as a Pathway to Stabilize Electrocatalysts
Xuyang Zhou, Olga Kasian, Ting Luo +8
Dissolution of electrocatalysts during long-term and dynamic operation is a challenging problem in energy conversion and storage devices such as fuel cells and electrolyzers. To de…
Effect of Pore Formation on Redox-Driven Phase Transformation
Xuyang Zhou, Yang Bai, Ayman A. El-Zoka +7
When solid-state redox-driven phase transformations are associated with mass loss, vacancies are produced that develop into pores. These pores can influence the kinetics of certain…
Understanding the degradation of a model Si-anode in Li-ion battery at the atomic-scale
Se-Ho Kim, Kang Dong, Huan Zhao +7
Si-anodes have long been candidates thanks to an expected ten-fold increase in capacity compared to graphite. However, details of the mechanisms governing their degradation remain…
Revisiting stress-corrosion cracking and hydrogen embrittlement in 7xxx-Al alloys at the near-atomic-scale
Martí López Freixes, Xuyang Zhou, Huan Zhao +4
Hydrogen embrittlement (HE) affects all major high-strength structural materials and as such is a major impediment to lightweighting e.g. vehicles and help reduce carbon-emissions…
Revealing in-plane grain boundary composition features through machine learning from atom probe tomography data
Xuyang Zhou, Ye Wei, Markus Kühbach +6
Grain boundaries (GBs) are planar lattice defects that govern the properties of many types of polycrystalline materials. Hence, their structures have been investigated in great det…
Understanding alkali contamination in colloidal nanomaterials to unlock grain boundary impurity engineering
Se-Ho Kim, Su-Hyun Yoo, Poulami Chakraborty +10
Metal nano-aerogels combine a large surface area, a high structural stability, and a high catalytic activity towards a variety of chemical reactions. The performance of such nanost…
Convolutional neural network-assisted recognition of nanoscale L12 ordered structures in face-centred cubic alloys
Yue Li, Xuyang Zhou, Timoteo Colnaghi +6
Nanoscale L12-type ordered structures are widely used in face-centred cubic (FCC) alloys to exploit their hardening capacity and thereby improve mechanical properties. These fine-s…
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…
