Effect of dislocation substructure on the primary creep behavior of alpha titanium at elevated temperature
… are swept from the lattice by moving dislocations. The prestrained and recovered samples tested at 60006 did not show a creep arrest. This is attributed to even distribution of interstitials on the recovered dislocation substructure making dynamic strain aging less effective. …

Ductility in high chromium super-ferritic alloys
… phases. The ductility is enhanced by raising the mobile dislocation density, and this may be achieved by pre-straining recrystallised material, or increasing the number of dislocation sources in the otherwise source-poor material. The generation of mobile dislocations by prismatic punching at …

Interplay between mineral reaction and deformation via structural defects
… systems in the calcite single crystal and more mobile dislocations in the magnesio-calcite grains, providing fast diffusion pathways. In torsion experiments a gradual decrease in dolomite and magnesio-calcite layer thickness was observed at a critical shear strain. During deformation, …
