Strain gradients and geometrically necessary dislocations in deformed ice single crystals

Scripta Materialia, 2003
Abstract Hard X-ray diffraction experiments were performed on ice single crystals deformed in torsion. This work shows the relationship between the density of geometrically necessary dislocations and strain gradients. The torsion strain appears to be totally accommodated by geometrically necessary basal screw dislocations.

Evolution of geometrically necessary dislocations in plastically strained precipitation hardened materials

International Journal of Microstructure and Materials Properties, 2011
There has recently been a strong interest in modelling size-dependent plasticity in metals based on the concept of geometrically necessary dislocations (GNDs). However, the precise manner by which geometrically necessary dislocations interact with second-phase particles remains elusive.
