First In Situ Observation of Partial Dislocation-Mediated Plastic Flow in Shocked Single-Crystal Aluminum

Ultrafast Science
In single-crystal aluminum (Al), partial dislocations are believed to play a crucial role in plasticity under extreme loading conditions; however, their activation has seldom been observed in experiments.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing
