This schematic illustration shows the generation of dislocation arrays during the liquid-phase compaction process. The Te liquid (red) between the Bi0.5Sb1.5Te3 grains flows out during the compacting ...
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 ...
