Abstract: Persistent slip band (PSB) is an important and typical microstructure generated during fatigue crack initiation. Intensive work has been done to investigate the mechanisms of the formation of persistent slip bands since the 1950s when… read more here.

Abstract: Disentangling fatigue Metal fatigues when repeatedly loaded, ultimately failing when cracks form and propagate through the material. Lavenstein et al. studied the origins of this process in nickel. Using high-resolution observations, they tracked how dislocations… read more here.
