While predetermining mechanical properties supports this process, specifying grain size means that post-processing steps including drawing, coining, stamping, and machining turn-over lower scrap rates ...

Nowadays, most studies utilizing diffraction contrast tomography, either in the lab or at the synchrotron, have concentrated on relatively low-aspect-ratio samples, usually rectangular or cylindrical ...

ITHACA, N.Y. -- Just as a snowflake’s intricate structure vanishes when it melts and transforms when it refreezes, the microstructure of metals can change during the 3D printing process, resulting in ...
