Domain Boundaries in a Metallic Distortive Polar Metal
Adrian Savovici, Barak Ratzker, Xuyang Zhou +12
Polar metals are an underexplored material class combining two properties that are typically incompatible, namely a polar crystal structure and reasonable electrical conductivity.…
Secondary Grain Boundary Dislocations Alter Segregation Energy Spectra
Xinren Chen, William Gonçalves, Yi Hu +9
Grain boundaries (GBs) trigger structure-specific chemical segregation of solute atoms. According to the three-dimensional (3D) topology of grains, GBs - although defined as planar…
Complexions at the Iron-Magnetite Interface
Xuyang Zhou, Baptiste Bienvenu, Yuxiang Wu +3
Synthesizing distinct phases and controlling the crystalline defects in them are key concepts in materials and process design. These approaches are usually described by decoupled t…
Interstitial segregation has the potential to mitigate liquid metal embrittlement in iron
Ali Ahmadian, Daniel Scheiber, Xuyang Zhou +6
The embrittlement of metallic alloys by liquid metals leads to catastrophic material failure and severely impacts their structural integrity. The weakening of grain boundaries by t…
