The problem of sliding at a nonplanar grain boundary is considered in detail. The stress field, and sliding displacement and velocity can be calculated at a boundary with a shape which is periodic in the sliding direction (a wavy or stepped grain boundary): a) when deformation within the crystals which meet at the boundary is purely elastic, b) when diffusional flow of matter from point to point on the boundary is permitted. The results give solutions to the following problems. 1) How much… Expand
The contribution of grain boundary sliding to axial strain during diffusion creep
Abstract Grain boundary sliding is necessary during diffusion creep to maintain continuity across the grain boundaries. In this paper it is shown, by use of a two-dimensional hexagonal array, thatExpand
Diffusional creep and diffusionally accommodated grain rearrangement
Abstract An analysis is made of the normal tractions acting on grain boundaries in a solid with a perfectly regular hexagonal grain structure deforming via diffusional creep. Restrictions are placedExpand
Grain boundary sliding and diffusion creep
Abstract The theory of diffusion creep is reviewed. It is shown that if a polycrystalline material is to deform in a coherent manner without the development of voids, grain boundary sliding isExpand
Grain-boundary sliding and crack nucleation in ice
Abstract Using a special geometry of columnar ice samples, we studied the process of grain-boundary sliding (GBS) in ice and its role in crack nucleation. It is shown that GBS is a viscous processExpand
Viscous grain-boundary sliding and grain rotation accommodated by grain-boundary diffusion
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-balanceExpand
Cavity nucleation at particles on sliding grain boundaries. A shear crack model for grain boundary sliding in creeping polycrystals
Abstract The paper summarizes the results of classical nucleation theory applied to the nucleation of creep cavities at hard second-phase particles. Stress concentrations at particles in slidingExpand
The role of grain boundary mobility in diffusional deformation
Abstract The model of diffusional deformation is revisited by accounting for the dependence of the diffusion potential on grain boundary curvature. The issue is developed through the analysis of twoExpand
Simulation of diffusional creep accompanied by grain growth in two-dimensional polycrystalline solids
Abstract Creep deformation is simulated in a two-dimensional polycrystalline aggregate by incorporating a dynamic grain growth model, where diffusive matter along grain boundaries contributes toExpand
Diffusion-accommodated sliding of irregularly shaped grain boundaries
The diffusion-accommodated sliding of irregularly shaped grain boundaries in two-dimensional bicrystals is considered. The following assumptions are made: the grains adjoining the boundaries areExpand
Grain boundary sliding in the presence of grain boundary precipitates during transient creep
A constitutive rate equation for grain boundary sliding (GBS), in the presence of grain boundary precipitates, is developed. Langdon’s GBS model is modified by incorporating physically de-fined backExpand


Diffusional Viscosity of a Polycrystalline Solid
According to a suggestion of Nabarro, any crystal can change its shape by self‐diffusion in such way as to yield to an applied shearing stress, and this can cause the macroscopic behavior of aExpand
Mechanism for “Viscous” Grain-boundary Sliding
THERE is increasing interest in mechanisms which give plastic deformation at low stresses and moderately high or high temperatures (more than half the melting temperature Tm). Theories of diffusionalExpand
A Model for Boundary Diffusion Controlled Creep in Polycrystalline Materials
The creep rate (ė) predicted by the boundary diffusion (Db) model is ė≃150σDbWΩ/(GS)3kT, where σ is the stress, W is the boundary width, (GS) is the average grain size, and Ω is vacancy volume. TheExpand
