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 ...

Researchers have used machine learning to design nano-architected materials that have the strength of carbon steel but the lightness of Styrofoam. The team describes how they made nanomaterials with ...

Resembling the interlocking links in chainmail, novel nanoscale material is incredibly strong and flexible. The interlocked material contains 100 trillion mechanical bonds per 1 square centimeter -- ...

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 ...

Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel (CrCoNi). Not only is the metal extremely ...
