Zonal dislocations in Laves phases: A coupled synchro-shear slip mechanism
Sang-Hyeok Lee, Mariano Forti, Thomas Hammerschmidt +6
Synchro-shear is the primary plastic deformation mechanism in Laves phases at elevated temperatures, mediated by synchro-Shockley partial dislocations-zonal dislocations that proce…
EBSD and Subtle Crystallographic Differences - A Study of Resolving Interlayer Spacings in Nb-Ni and Nb-Co mu-phases
Lukas Berners, Nisa Ulumuddin, Annika Baum +9
In ordered intermetallics, slight variations in lattice site occupancy and specific interlayer spacings have been identified as the sources of significant changes in critical resol…
Machine learning-enabled tomographic imaging of chemical short-range atomic ordering
Yue Li, Timoteo Colnaghi, Yilun Gong +13
In solids, chemical short-range order (CSRO) refers to the self-organisation of atoms of certain species occupying specific crystal sites. CSRO is increasingly being envisaged as a…
Solute Induced Defect Phase Transformations in Mg Grain Boundaries
P. Mathews, S. Zhang, C. Scheu +3
The study of defect phases is important for designing nanostructured metals and alloys. Grain boundaries (GBs) form one class of defects that directly influence materials propertie…
Contribution of the oxygen reduction reaction to the electrochemical cathodic partial reaction for Mg-Al-Ca solid solutions
Markus Felten, Siyuan Zhang, Rasa Changizi +5
The electrochemical corrosion rate of Magnesium (Mg) and Mg alloys depends on the stability of the formed surface layer. Based on the Mg substrate, the oxide structure comprises a…
Metastable defect phase diagrams as a tool to describe chemically driven defect formation: Application to planar defects
A. Tehranchi, S. Zhang, A. Zendegani +3
Thermodynamic bulk phase diagrams have become the roadmap used by researchers to identify alloy compositions and process conditions that result in novel materials with tailored mic…
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…
Chemical and structural characterization of the native oxide scale on a Mg-based alloy
Deborah Neuß, Ingrid E. McCarroll, Siyuan Zhang +11
In this study, the structure and composition of the native oxide forming on the basal plane (0001) of Mg-2Al-0.1Ca is investigated by a correlative approach, combining scanning tra…
Revealing compositional evolution of PdAu electrocatalyst by atom probe tomography
Leonardo Shoji Aota, Se-Ho Kim, Chanwon Jung +2
Pd-based electro-catalysts are a key component to improve the methanol oxidation reaction (MOR) kinetics from alcohol fuel cells. However, the performance of such catalysts is degr…
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…
Elemental (im-)miscibility determines phase formation of multinary nanoparticles co-sputtered in ionic liquids
Michael Meischein, Alba Garzón-Manjón, Thomas Hammerschmidt +5
Non-equilibrium synthesis methods allow to alloy bulk-immiscible elements into multinary nanoparticles, which broadens the design space for new materials. Whereas sputtering onto s…
