Study Notes
Materials Science and Engineering
- Materials Science: Study of underlying relationships between processing, structure, and properties of materials
- Materials Engineering: Translation of materials into useful structures or devices
Importance of Materials Science
- Applied scientists and engineers must make material choices based on several criteria:
- In-service conditions
- Properties (strength, ductility, malleability)
- Environment
- Economics (cost of finished product)
Classification of Materials
- 6 main classifications of materials:
-
- Metals (e.g., Steel, Copper)
-
- Ceramics (e.g., Quartz, Alumina)
-
- Composites (e.g., Fiberglass, Asphalt)
-
- Polymers (e.g., Nylon, Rubber)
-
- Semiconductors (e.g., Silicon, Gallium Nitride)
-
- Biomaterials (used in medical implants, e.g., hip replacement)
-
