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 ...

Ductility, i.e., uniform strain achievable in uniaxial tension, diminishes for materials with very high yield strength. Even for the CrCoNi medium-entropy alloy (MEA), which has a simple face-centered ...
