Scientists at Nagoya University in Japan harnessed the power of artificial intelligence to unveil a novel approach to comprehend small defects known as dislocations in polycrystalline materials.

A shock wave traveling through a material can create defects known as dislocations – tiny shifts in the material’s crystal that propagate through it, leaving what are known as stacking faults behind.

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

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 ...
