Shear melting and high temperature embrittlement: theory and application to machining titanium [PDF]
Physical Review Letters 114 165501 2015, 2015 We describe a dynamical phase transition occurring within a shear band at high temperature and under extremely high shear rates. With increasing temperature, dislocation deformation and grain boundary sliding is supplanted by amorphization in a highly localized nanoscale band, which allows massive strain and fracture.

The influence of alloying on slip intermittency and the implications for dwell fatigue in titanium [PDF]
, 2022 Dwell fatigue, the reduction in fatigue life experienced by titanium alloys due to holds at stresses as low as 60% of yield, has been implicated in several uncontained jet engine failures. Dislocation slip has long been observed to be an intermittent, scale-bridging phenomenon, similar to that seen in earthquakes but at the nanoscale, leading to the ...
