Dendritic deformation modes in additive manufacturing revealed by operando x-ray diffraction
Abstract Dynamic solidification behavior during metal additive manufacturing directly influences the as-built microstructure, defects, and mechanical properties of printed parts. How the formation of these features is driven by temperature variation (e.g., thermal gradient magnitude and solidification front velocity) has been studied extensively in metal additive manufacturing, with synchrotron x-ray imaging becoming a critical tool to monitor these processes. Here, we extend these efforts to monitoring full thermomechanical deformation during solidification through the use of operando x-ray diffraction during laser melting. With operando diffraction, we analyze thermomechanical deformation modes such as torsion, bending, fragmentation, assimilation, oscillation, and interdendritic growth. Understanding such phenomena can aid the optimization of printing strategies to obtain specific microstructural features, including localized misorientations, dislocation substructure, and grain boundary character. The interpretation of operando diffraction results is supported by post-mortem electron backscatter diffraction analyses.
Exploiting grain boundary diffusion to minimize dendrite formation in lithium metal-solid state batteries
A multi-scale model reveals that the microstructure of the Li metal anode can impact the performance of solid-state batteries. Micron-sized, columnar grains are preferred for minimizing void formation at the solid electrolyte interface.
