Insights into the microscopic details of 3D printing from the Swiss Light Source SLS could propel the technology toward wider application
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.
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 is an effective method to engineer microstructures of additively manufactured Ti6Al4V3Fe alloys.
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.
A new simulation of the most dangerous radioactive debris from the Fukushima nuclear power plant will help with clean-up efforts.
Direct observation of crack formation mechanisms with operando Laser Powder Bed Fusion X-ray radiography
Operando high-speed X-ray radiography experiments reveal the cracking mechanism during 3D laser printing of a Ni superalloy.
Full-field X-ray absorption tomography reveals the chemical structure of defects in metal-organic frameworks
Cryo-full-field XANES computed tomography was used to visualize the presence and distribution of a second coordination polymer of reduced copper coordination within defect-engineered HKUST-1 MOF crystals. Observations encourage a revisitation of the structure-property relationships of defect-engineered MOFs.
