UCLA breaks new ground in alloy research, presenting the first 3D mapping of medium and high-entropy alloys, potentially revolutionizing the field with enhanced toughness and flexibility in these materials. Alloys, which are materials such as steel that are made by combining two or more metallic
UCLA-led team maps medium- and high-entropy alloys, identifies potential to tune their properties, making them both stronger and more flexible.
The UCLA-led research could revise a 70-year-old model of how the fundamental building blocks of substances are assembled.
— a discovery that may have implications for future technological developments. Published in the journal Nature Communications, the study showed that by adding trace amounts of plastic to a solution, researchers were able to create a crystalline structure in a matter of minutes. Peter Ercius, a Berkeley Lab scientist who helped visualize the crystals, said before this discovery, nanoparticles were typically altered through “self-assembly.” “If something self-assembles, it kind of doesn’t matter what you do,” Ercius said. “It’s just going to do its own thing.” The preexistin...
3D Atomic Imaging Helps Observe Metallic Glass Structure Written by AZoNanoApr 1 2021 Amorphous solids, which also include rubber, glass and plastics, are a class of matter. But despite their routine applications in people’s day-to-day lives, amorphous solids have traditionally presented a challenge to researchers. At left, an experimental 3D atomic model of a metallic glass nanoparticle, 8 nanometers in diameter. Right, the 3D atomic packing of a supercluster within the structure, with differently colored balls representing different types of atoms. Image Credit: University of California...
