MSE Terminology
- Burger's Vector:
- Denotes magnitude and direction of lattice distortion
- Ductiility:
- Plastic deformation a solid can withstand (% elongation, area reduction)
- Edge Dislocation:
- An extra plane of atoms is inserted into the lattice
- Fractography:
- The study of failure, including fracture, fatigue, and creep.
- Hardness:
- The ability to resist surface deformation
- Interstitial Atom:
- An atom placed between atoms in a crystal lattice
- Interstitial Site:
- Place between atoms in a crystal lattice where another atom could fit.
- Metallography
- Taking pictures of magnified samples of metals to learn of constituents and grain structure.
- Resilience
- Energy absorbed before permanent deformation
- Screw Dislocation
- Atoms are one unit away from where they should be
- Stiffness:
- Stress per deformation
- Strength:
- Stress limit for material
- Toughness:
- Static toughness: integral of ð over €
- Vacancy:
- A place in the crystal lattice that should contain an atom, but does not
