In metallic materials, the process of grain growth is also the process of grain boundary migration. So what role does atomic diffusion play in this process? Is there long-range diffusion migrating between grains, a process similar to transport; or is there diffusion within grains, where grain torsion occurs; or is it some other process.
Atomic diffusion is crucial in the grain growth process of metallic materials. It involves the movement of atoms within the material, facilitating grain boundary migration. Long-range diffusion allows atoms to travel over larger distances, contributing to the rearrangement and coalescence of grains during the grain growth process. This diffusion is essential for the evolution of microstructures in metallic materials.
In the process of grain growth, atomic diffusion primarily occurs along grain boundaries, contributing to grain boundary migration. This migration is crucial for the coalescence and rearrangement of grains. While there can be some diffusion within grains, the emphasis is often on the long-range diffusion between grains, facilitating their movement and growth. This process helps determine the final microstructure of the metallic material.
