For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that ...

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

This is a preview. Log in through your library . Abstract Experiments by transmission electron microscopy on thin foils of stainless steel have enabled the interaction of dislocations on different ...

Researchers used Argonne's Advanced Photon Source to capture how the microstructure of metals evolves in real time during 3D printing. The findings could pave the way for advanced manufacturing of ...
