Grain boundary diffusion is a commonly observed route for solute migration in polycrystalline materials. It dominates the effective diffusion rate at lower temperatures in metals and metal alloys. Take the apparent self-diffusion coefficient for single-crystal and polycrystal silver, for example. See more The grain boundary diffusion coefficient is the diffusion coefficient of a diffusant along a grain boundary in a polycrystalline solid. It is a physical constant denoted $${\displaystyle D_{b}}$$, and it is important in … See more The general way to measure grain boundary diffusion coefficients was suggested by Fisher. In the Fisher model, a grain boundary is represented as a thin layer of high … See more • Kirkendall effect • Phase transformations in solids • Mass diffusivity See more WebOct 30, 2000 · DOI: 10.1016/S1359-6462(00)00518-2 Corpus ID: 135727356; Grain boundary penetration of nickel by liquid bismuth as a film of nanometric thickness @article{Mari2000GrainBP, title={Grain boundary penetration of nickel by liquid bismuth as a film of nanometric thickness}, author={N.
