Material Science Lecture Notes

These flashcards cover key concepts and definitions related to material science discussed in the lecture.

Material Science

The study of the relationships between the structures and properties of materials.

Ceramics

Compounds between metallic and nonmetallic elements, often oxides, nitrides, and carbides, characterized by high hardness and brittleness.

Polymers

Large molecules formed from repeating smaller units (mers), typically composed of hydrocarbons and often chemically inert.

Metals

Solid materials that exhibit properties such as stiffness, strength, ductility, and resistance to fracture, comprised of metallic and nonmetallic elements.

Ionic Bonding

A type of chemical bond formed between a metal and a non-metal through the transfer of electrons.

Covalent Bonding

A type of bonding involving the sharing of electron pairs between atoms, typically seen in non-metals.

Metallic Bonding

The electrostatic attraction between positively charged metal ions and delocalized electrons in a metal structure.

Composite Materials

Materials made from two or more constituent materials with significantly different physical or chemical properties.

Crystal Structure

The orderly arrangement of atoms in a crystalline material, influencing its properties and behavior.

Atomic Structure

The arrangement of protons, neutrons, and electrons within an atom, determining its characteristics and behavior.
