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.
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.
Understanding variant selection and texture in additively manufactured red-gold alloys
Synchrotron X-ray diffraction experiments reveal the presence of a non- negligible amount of tetragonal phase in 3D printed red-gold samples.
