The role of dislocation slip on the activation of different twinning modes in...
Twinning is an important deformation mechanism in hcp metals like Zirconium. It is now accepted that, unless twinning is accounted for, the typical deformation textures in these... -
High strain rate studies of twinning
Where a material can plastically deform by more than one mechanism, the relative extent to which the various mechanisms operate often depends on the strain rate. Most metals... -
The effect of Oxygen on twinning in Zr model alloys
This experiment is aimed to study the effect of Oxygen on deformation mechanisms in Zr alloys with a particular emphasis on studying twinning. Oxygen is found in many Zr alloys... -
The influence of texture on mechanical twinning in calcite
We request 3 days of beam-time on ENGIN-X to investigate the influence of lattice preferred orientation on the onset of mechanical twinning in polycrystalline calcite (CaCO3)... -
Mechanical twinning in quartz rocks: in situ experiments at stress and during...
Previous experiments at ENGIN-X (Wenk et al. 2007) established that quartz rocks undergo mechanical twinning if stressed above 100 MPa. The amount of twinning is highly... -
Does elastic twinning play a role in the thermal expansion behaviour of polyc...
We request two days of beam-time on POLARIS to obtain high resolution measurements of the thermal expansion of dolomite [CaMg(CO3)2]. The experiment forms part of a larger... -
Investigation of the impact of mechanical twinning on the thermal expansion b...
We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite....
