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…
Stochastic twinning in confined volumes of Mg: Insights from in-situ micromechanical testing and atomistic simulations
Hexin Wang, Fatim Zahra Mouhib, Chunhua Tian +6
Tensile twinning plays a central role in accommodating <c>-axis plasticity in Mg. In bulk Mg, twinning typically shows a relatively deterministic response with a low critical stres…
Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows
Khalil Rejiba, Sang-Hyeok Lee, Christina Gasper +3
Defect phase diagrams provide a unified description of crystal defect states for materials design and are central to the scientific objectives of the Collaborative Research Centre…
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…
Automated Segmentation of Large Image Datasets using Artificial Intelligence for Microstructure Characterisation, Damage Analysis and High-Throughput Modelling Input
Setareh Medghalchi, Joscha Kortmann, Sang-Hyeok Lee +3
Many properties of commonly used materials are driven by their microstructure, which can be influenced by the composition and manufacturing processes. To optimise future materials,…
