Intergranular slippage on faceting boundaries with a bimodal distribution of facet dimensions
The speed of mutual displacement of the grains along faceting boundary with two characteristic sizes of facets under the external shear stress is considered. Based on the solution of the stationary equation of diffusion of vacancies at the grain boundary, the distribution of their concentration and...

| Sažetak: | The speed of mutual displacement of the grains along faceting boundary with two characteristic sizes of facets under the external shear stress is considered. Based on the solution of the stationary equation of diffusion of vacancies at the grain boundary, the distribution of their concentration and normal stresses along the facets is found. The presence of smaller facets leads to an increase in the speed of intergranular slippage. |
