Dislocation dynamics examines the behaviour of line defects within crystalline materials—imperfections that are central to understanding plastic deformation. At the microstructural level, the motion ...
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 ...
What is Hall-Petch Strengthening? Hall-Petch strengthening is a phenomenon where decreasing the average grain size of a material leads to increased yield strength and hardness. This effect is ...
