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…
Defect-controlled twin activation in crystallographically equivalent magnesium micropillars
Hexin Wang, Fatim Zahra Mouhib, Chunhua Tian +6
Tensile twinning plays a central role in accommodating <c>-axis plasticity in Mg. In bulk Mg, it typically shows a relatively deterministic response with a low critical stress, whe…
AlloyVAE: A generative model for complex probabilistic field-to-field relationships in alloys
Ningyu Yan, Zhuocheng Xie, Kai Guo +3
The inherent compositional heterogeneity of multi-principal element alloys (MPEAs) gives rise to complex, spatially varying mechanical fields that cannot be uniquely determined fro…
Chemically tailored planar defect phases in the Ta-Fe μ-phase
Christina Gasper, Nisa Ulumuddin, Siyuan Zhang +5
Intermetallics often exhibit complex crystal structures, which give rise to intricate defect structures that critically influence their mechanical and functional properties. Despit…
First-Principles Insights into the Site Occupancy of Ta-Fe-Al C14 Laves Phases
Nisa Ulumuddin, Sandra Korte-Kerzel, Zhuocheng Xie
This study investigates the site occupancy preferences of Al in Ta(FeAl) Laves phases using first-principles calculations, covering Al concentrations from 0 to 50 a…
Beyond Fundamental Building Blocks: Plasticity in Structurally Complex Crystals
Tobias Stollenwerk, Pia Carlotta Huckfeldt, Nisa Zakia Zahra Ulumuddin +3
Intermetallics, which encompass a wide range of compounds, often exhibit similar or closely related crystal structures, resulting in various intermetallic systems with structurally…
Grain boundary segregation spectrum in basal-textured Mg alloys: From solute decoration to structural transition
Anumoy Ganguly, Hexin Wang, Julien Guénolé +4
Mg alloys are promising lightweight structural materials due to their low density and excellent mechanical properties. However, their limited formability and ductility necessitate…
Predicting Grain Boundary Segregation in Magnesium Alloys: An Atomistically Informed Machine Learning Approach
Zhuocheng Xie, Achraf Atila, Julien Guénolé +3
Grain boundary (GB) segregation in magnesium (Mg) substantially influences its mechanical properties and performance. Atomic-scale modelling, typically using ab-initio or semi-empi…
Influence of chemical composition on the room temperature plas-ticity of C15 Ca-Al-Mg Laves phases
Martina Freund, Zhuocheng Xie, Pei-Ling Sun +8
The influence of chemical composition changes on the room temperature mechanical proper-ties in the C15 CaAl2 Laves phase were investigated in two off-stoichiometric compositions w…
