Thermal and phase evolution during laser powder bed fusion of Al-Sc-Zr elemental powder blends
The reaction of elemental scandium and zirconium powders with liquid aluminum is observed directly via operando X-ray diffraction during laser 3D printing. This work demonstrates that elemental blends can be used to create fine-grained crack-free Al-alloys and highlights the importance of feature size.
Into the fourth dimension: time-resolved soft X-ray laminography
Combining time-resolved soft X-ray STXM imaging with magnetic laminography, researchers were able to investigate magnetization dynamics in a ferromagnetic microstructure resolved in all three spatial dimensions and in time. Thanks to the possibility of freely selecting the frequency of the excitation applied to the magnetic element, this technique opens the possibility to investigate resonant magneto-dynamical processes, such as e.g. magnetic vortex core gyration and switching, and spinwave emission.
