Study Notes
Material Science
- Material science is an interdisciplinary field that studies the relationships between the processing, structure, and properties of materials to design and discover new materials.
- It involves crystallography, bonding, thermodynamics, and kinetics to understand the properties of materials.
Tasks of Materials Scientists/Engineers
- Develop, process, and test materials
- Research material properties and structures
- Assess whether materials meet mechanical, electrical, and/or chemical requirements
- Select materials for specific products
- Discover new ways to use existing materials
- Determine causes of failures and find appropriate solutions
- Evaluate and reduce environmental impacts
- Analyze cost effectiveness
- Manage projects and teams
- Consult with other engineers and scientists
- Write proposals, budgets, and reports
Why Study Material Science and Engineering?
- Material science teaches us what things are made of and why they behave as they do.
- Material engineering shows us how to apply knowledge to make better things and to make things better.
Subfields of Material Science
- Nanotechnology: study of materials with a width ranging from less than 1 nanometer to 100 nanometers
