The brittle-to-ductile transition in silicon
Recent experiments on the brittle-ductile transition (BDT) of precracked specimens of Si show that the transition is sharp, and that the strain rate dependence of the transition temperature, Tc, is controlled by dislocation velocity. Etch pit observations show that dislocation generation from the crack tip begins at K just below KIc, from a small ...

The material deformation modes of monocrystalline gallium antimonide (GaSb) under nano-scratching
The deformation characteristics of GaSb are investigated by employing nano-scratch tests to understand the material removal mechanism during ultra-precision grinding.

The brittle-to-ductile transition in germanium
Abstract The brittle-to-ductile transition in precracked germanium crystals has been studied experimentally. Germanium undergoes a “smooth” brittle-ductile transition, where the stress to fracture rises steadily with temperature, associated with dislocation activity around the crack front at temperatures well below the transition temperature.

Dislocation dynamics and brittle-to-ductile transitions
Abstract The validity of different types of models for crack-dislocation interactions and their effect on fracture is discussed. The brittle-to-ductile transition (BDT) in precracked silicon and sapphire can be described by a two-stage dynamic model based on dislocation motion to and around the crack tip.

Rheological transitions in the middle crust: insights from Cordilleran metamorphic core complexes [PDF]
High-strain mylonitic rocks in Cordilleran metamorphic core complexes reflect ductile deformation in the middle crust, but in many examples it is unclear how these mylonites relate to the brittle detachments that overlie them.

The discovery of slow earthquakes illuminates the existence of a strange depth dependence of seismogenesis, which contradicts the common understanding of smooth brittle/seismic‐ductile/aseismic transition as going deeper into the earth's surface layers ...
