Spatiotemporal slip dynamics during deformation of gold micro-crystals

Intermittent plastic deformation in micro-crystals was resolved in both space and time, yielding velocity profiles that peak in a range from approximately 1 μm/s to 100 μm/s. The peak velocities exhibit a broad, close to scale-free distribution, with a scaling regime at high velocities that is compa...
