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 ...

Solute clustering in the Mg-2at.%Zn alloy predicted by atomistic simulations. Over the last couple of decades, researchers have been able to demonstrate that tiny groupings of solute atoms at the ...

Ling Li, an assistant professor in mechanical engineering at Virginia Tech, has found insights into building stronger and tougher ceramics by studying the shells of bivalve mollusks. This perspective ...

Materials scientists have recently discovered a new mechanism to increase the strength and ductility of a high-entropy alloy, two properties which normally vary inversely with each other. The findings ...

In addition to adding strength, this design allows the structure to use its crack patterns to minimize damage into the inner shell. Ling Li, an assistant professor in mechanical engineering at ...
