Study Notes
Introduction to Materials Science and Engineering
- Materials science and engineering (MSE) is an interdisciplinary field that involves inventing new materials and improving existing ones by understanding the relationships between microstructure, composition, synthesis, and processing.
Key Concepts
- Composition refers to the chemical make-up of a material.
- Structure refers to the arrangement of atoms, observed at different levels of detail.
Roles of Materials Scientists and Engineers
- They develop new materials and improve existing ones.
- They deal with the synthesis and processing of materials.
- They are involved in manufacturing processes related to component production.
Synthesis and Processing
- Synthesis refers to how materials are made from naturally occurring or man-made chemicals.
- Processing refers to how materials are shaped into useful components.
Relationships Between Properties and Performance
- Materials scientists and engineers establish relationships between a material's properties and its performance.
- The structure of a material significantly influences its properties, even if the composition remains unchanged.
Microstructure
- Microstructure refers to microscopic changes in a material's structure.
- Understanding microstructure is key to controlling a material's properties.
Example: Ceramic Superconductors
- Ceramic superconductors were invented in 1986.
- These materials can carry electrical current without resistance under certain conditions.
- The discovery of superconducting behavior in ceramic materials was unexpected.
The Tetrahedron of Materials Science and Engineering
- The tetrahedron consists of microstructure, synthesis and processing, composition, and properties.
- These components are interconnected and affect the performance-to-cost ratio.
