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
- Crystallography: study of arrangement of atoms in a crystalline solid and their physical properties
- Materials Characterization: acquiring information about materials through various techniques
- Metallurgy: study of metals and their alloys, including extraction, microstructure, and processing
- Tribology: study of the wear of materials due to friction and other factors
- Surface Science: study of structures and interactions at interfaces of solids and gases, liquids, and solids
- Glass Science: study of non-crystalline materials
- Rheology: study of materials that flow, including non-Newtonian fluid dynamics
- Thermodynamics, Statistical Mechanics, Chemical Kinetics, and Physical Chemistry: study of phase stability and physical and chemical transformations
- Mechanics of Materials: study of mechanical properties of materials and their structural applications
- Solid-State Physics and Quantum Mechanics: study of electronic, thermal, magnetic, chemical, structural, and optical properties of materials
- Biology: study of integration of materials into biological systems
- Continuum Mechanics and Statistics: study of fluid flows and ensemble systems
- Diffraction and Wave Mechanics: characterization of materials
Types of Engineering Materials
- Metals and Alloys: include Steels, Aluminum, Magnesium, Zinc, Cast iron, Titanium, Copper, and Nickel
- Semiconductors: include Silicon, Germanium, and Gallium Arsenide-based semiconductors
- Composite Materials: formed from two or more materials, producing properties not found in any single material
- Biomaterials: used in components implanting into the human body for replacement of diseased or damaged parts
Bonding in Materials
- Metallic Bonding: type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions
- Covalent Bonding: materials characterized by bonds formed by sharing of valence electrons among two or more atoms
- Ionic Bonding: bond between a metal and a non-metal that is responsible for holding oppositely charged ions together by a strong electrostatic attraction
