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. …

The Influence of Substructure and Dislocation Mobility on the Creep Properties of Some Single Phase Metals
… metal, is closely related to the mobility of mobile dislocations, rather than to an internal resistance arising from the substructure. To explain the observed mechanical responses, a model has been proposed which provides some semi-quantitative predictions of material behaviour. Both the …

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 …

An improved dislocation density based work hardening model for Al-Alloys
… at low temperatures. The 3IVM considers edge dislocations, and hence only dislocation climb as a possible recovery mechanism. However, cross slip can be the ruling recovery process especially at low temperatures. Another shortcoming of the model is the neglection of the interaction of mobile …

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, …
