Effect of grain boundary structures on grain boundary sliding in magnesium

Materials Letters, 2012
Abstract The effect of grain boundary structures on the deformation behavior at the grain boundaries in magnesium was examined by the nanoindentation creep test. The results of the nanoindentation creep test showed that the dominant deformation mechanism around the grain boundary was grain boundary sliding; however, the occurrence of grain boundary ...

Viscous grain-boundary sliding and grain rotation accommodated by grain-boundary diffusion

Acta Materialia, 2005
When the sliding of a viscous grain boundary is accommodated by grain-boundary diffusion, we evaluate the sliding rate and the stress distribution on the boundary, by employing the energy-balance method developed by Mori et al. [Mori T, Nakasone Y, Taya M, Wakashima K. Phil Mag Lett 1997;75:359 and Mori T, Koda M, Monzen R, Mura T.

Tracking the sliding of grain boundaries at the atomic scale

Science, 2022
Grain boundaries (GBs) play an important role in the mechanical behavior of polycrystalline materials. Despite decades of investigation, the atomic-scale dynamic processes of GB deformation remain elusive, particularly for the GBs in polycrystals, which are commonly of the asymmetric and general type.

Grain Boundary Sliding at Serrated Grain Boundaries

Advanced Performance Materials, 1997
A constitutive model is developed for grain boundary sliding (GBS) at serrated grain boundaries. Based on a previously developed GBS model, using the dynamics of grain boundary dislocation pile-up, the present model takes the average of the sliding rate over the characteristic dimensions of grain boundary serrations.

Dislocations in grain boundaries and grain boundary sliding

Acta Metallurgica, 1967
Abstract The Burgers vectors of grain boundary dislocations were analyzed by transmission electron microscopy in creep tested iron and iron alloys. The analysis indicates that the dislocations retain their original Burgers vectors when joining grain boundaries and remain undissociated. It is suggested that grain boundary sliding in creep is caused by
