..., regardless of the crystal structure, if the grains have a random orientation. Then, Fick's law, with one effective diffusivity, would apply. However, polycrystalline materials contain grain boundaries that are high-diffusivity paths for diffusion. This can lead to surprising amounts of diffusion but normally...
