This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Character and Distribution of Geometrically Necessary Dislocations in Polycrystalline Tantalum
Microscopy and Microanalysis, 2023Abstract Geometrically necessary dislocations (GNDs) play a key role in accommodating strain incompatibility between neighboring grains in polycrystalline materials. One critical step toward accurately capturing GNDs in deformation models involves studying the microstructural features that promote GND accumulation and the resulting ...

Abstract The concept of statistically stored and geometrically necessary dislocations is discussed in terms of observed deformation microstructures subdivided by incidental dislocation and geometrically necessary boundaries. This discussion is illustrated by examples of microstructures formed under conditions of homogeneous and nonhomogeneous ...
