Atomic Structure (Influence on Properties)

The arrangement of atoms in a material, which influences its chemical, thermal, and electrical properties.

Microscopic Structure (Definition)

The structure of a material on a microscopic scale, including grain size, distribution, orientation, and defects.

Macroscopic Structure

Features visible to the naked eye, such as porosity, cracks, and coatings.

Crystal Structure (Influence on Properties)

The way atoms are arranged in a material, influencing its ductility and formability.
