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 ...

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 ...

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 ...

Engineers devised a new method for designing metals and alloys that can withstand extreme impacts, which could lead to the development of automobiles, aircraft and armor that can better endure ...

(Nanowerk News) An international team of researchers, led by Professor Yu Zou (MSE), is using electric fields to control the motion of material defects. This work has important implications for ...
