TL;DR: In this paper, a crack between two single crystals of aluminum joined by a thin ductile interlayer of tin is introduced via selective chemical etching and can be considered sharp; the material surrounding the tip is fully annealed.

TL;DR: In this paper, two distinct approaches are commonly invoked to explain the brittle to ductile transition of a material in the presence of a crack: dislocation mobility plays the key role and the competition between crack tip dislocation nucleation and cleavage failure is reconciled.
Abstract: Two distinct approaches are commonly invoked to explain the brittle to ductile transition of a material in the presence of a crack. In one approach, dislocation mobility plays the key role. In the other approach, the competition between crack tip dislocation nucleation and cleavage failure plays the key role. The two approaches are reconciled in the present study.
