| 词条 | Grain Boundary Sliding |
| 释义 |
MechanismsHomogeneous deformation in a polycrystalline solid cannot be achieved by grain boundary sliding alone. The grain movements must be accommodated with either diffusion[2] or with dislocation motion.[3] In the Earth's upper mantle, dislocation-accommodated grain boundary sliding is expected to be the dominant deformation mechanism for olivine.[4] References1. ^Joachim Rösler, Harald Harders, Martin Bäker, Mechanical Behaviour of Engineering Materials, Springer-Verlag Berlin Heidelberg, 2007, p 396. {{ISBN|978-3-540-73446-8}} 2. ^Raj, R., and M.
