Fabrication and extreme micromechanics of additive metal microarchitectures
Sung-Gyu Kang, Barbara Bellon, Lalithkumar Bhaskar +14
The mechanical performance of metallic metamaterials with 3-dimensional solid frames is typically a combination of the geometrical effect ("architecture") and the characteristic si…
Stable nanofacets in [111] tilt grain boundaries of face-centered cubic metals
Tobias Brink, Lena Langenohl, Swetha Pemma +2
Grain boundaries can dissociate into facets if that reduces their excess energy. This, however, introduces line defects at the facet junctions, which present a driving force to gro…
Microstructure of a spark-plasma-sintered Fe2VAl-type Heusler alloy for thermoelectric application
Leonie Gomell, Imants Dirba, Hanna Bishara +8
The influence of microstructure on thermoelectricity is increasingly recognized. Approaches for microstructural engineering can hence be exploited to enhance thermoelectric perform…
Effect of the atomic structure of complexions on the active disconnection mode during shear-coupled grain boundary motion
Swetha Pemma, Rebecca Janisch, Gerhard Dehm +1
The migration of grain boundaries leads to grain growth in polycrystals and is one mechanism of grain-boundary-mediated plasticity, especially in nanocrystalline metals. This migra…
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…
