Extended Data Fig. 3: Effect of twinning defects on boundary migration and crack healing.

From: Autonomous healing of fatigue cracks via cold welding

Extended Data Fig. 3

Example of delayed crack healing that occurs when the defected twin boundary is replaced by a perfectly coherent twin boundary: (a) immediately after application of 0.2% tensile loading, (b) onset of closure at the crack tip 100 ps after application of loading, (c) propagation of a front of crack closure, (d) complete crack healing 160 ps after application of loading.
