microstructuregrain
Microstructure grain refers to the individual crystallites that make up a polycrystalline material. These grains are typically microscopic in size and are separated by grain boundaries, which are interfaces where the crystallographic orientation changes. The size, shape, and arrangement of these grains significantly influence the material's overall properties, including its mechanical strength, ductility, electrical conductivity, and optical transparency.
The formation of grains occurs during solidification from a liquid state or through solid-state transformations. Nucleation
Grain boundaries are regions of higher energy and disorder compared to the interior of the grains. They
