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…
Mechanical properties and deformation mechanisms of the C14 Laves and μ-phase in the ternary Ta-Fe(-Al) system
Christina Gasper, Elif Merve Soysal, Nisa Ulumuddin +4
As structural and functional materials, topologically close-packed (TCP) phases of transition metal compounds offer a wide range of attractive properties. Due to their complex crys…
Origins of limited non-basal plasticity in the μ-phase at room temperature
W. Luo, C. Gasper, S. Zhang +7
We unveil a new non-basal slip mechanism in the μ-phase at room temperature using nanomechanical testing, transmission electron microscopy and atomistic simulation. The (1-105) pla…
