Stacking fault tetrahedra (SFTs) are ubiquitous vacancy‐cluster defects in face‐centred cubic (FCC) metals, formed under conditions of plastic deformation, quenching or irradiation. Each SFT comprises ...
Stacking fault energy (SFE) is a fundamental parameter governing the formation and mobility of partial dislocations, mechanical twinning and phase transformations in metallic alloys. In face-centred ...
Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...
This X-ray radiographic image – similar to a medical X-ray, but taken at ultrafast speed with an X-ray laser – shows shock waves traveling through a diamond crystal. The initial wave is elastic. The ...
New GPU-accelerated modeling reveals the hidden mechanics behind graphene’s AB-BA transitions and the defects that freeze them in place. Study: Phase-Field Crystal Method for Bilayer Graphene. Image ...
