Knots are known for boosting the strength of materials, from the tiniest twists of DNA to (potentially) the very fabric of the universe. Now, Caltech engineers have developed a new material consisting ...

The mechanical strength and toughness of engineering materials are often mutually exclusive, posing challenges for material design and selection. To address this, a research team from The Hong Kong ...

Carbon steel is an iron-carbon alloy. Although pure iron is not intrinsically strong, adding carbon imparts great strength to this material. Crude iron, which is used in steel production, has a high ...

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 ...
