Study Notes
Material Structure
- The microstructure level of a material refers to the arrangement of atoms or molecules.
- The microstructure is typically examined at a length-scale of micrometers (μm) or nanometers (nm).
- The macrostructure level of a material refers to the overall shape and arrangement of the material.
Materials Science
- Engineers and scientists who study materials need to understand the relationships between the material's structure, properties, and behavior.
- The structure of a material has a profound influence on its properties and behavior.
