Permettre l’utilisation quotidienne de batteries lithium-air performantes
Les faisceaux de neutrons et la lumière synchrotron révèlent les processus chimiques qui se jouent dans les batteries lithium-air.
Additive manufacturing of alloys with programmable microstructure and properties
Using laser powder bed fusion (LPBF) technology, we devise special processing strategies to ‘program’ the thermal stability of the as-printed alloy, such that it is possible to decide, a priori, how the material’s microstructure will evolve upon heat treatment

X-rays make 3D metal printing more predictable
Insights into the microscopic details of 3D printing from the Swiss Light Source SLS could propel the technology toward wider application
Solidification modes during additive manufacturing
The thermal conditions during laser-based additive manufacturing are inferred from high-speed X-ray diffraction data and can be linked to a model for rapid solidification.
Thermal cycling during 3D laser printing
High-speed in situ X-ray diffraction is used to measure temperature profiles and cooling rates during 3D printing of a a Ti-6Al-4V single-track wall.
In situ alloying during additive manufacturing
In situ alloying is an effective method to engineer microstructures of additively manufactured Ti6Al4V3Fe alloys.
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.
