Crystal Defects: Vacancies and Self-Interstitials

The equilibrium number of vacancies N𝜐 for a given quantity of material depends on and increases with ______.

A self-interstitial is an atom from the crystal that is crowded into an ______ site.

A solid solution forms when the crystal structure is maintained and no new structures are formed, and there are two types: substitutional and ______.

For substitutional solid solutions, solute or impurity atoms replace or substitute for the host ______.

Appreciable quantities of a solute may be accommodated in a solid solution only when the difference in atomic radii between the two atom types is less than about ±15% which is known as the Atomic size ______.

A metal has more of a tendency to dissolve another metal of higher ______ than to dissolve one of a lower valency.

A dislocation is a linear or one-dimensional defect around which some of the atoms are ______.

There are two types of dislocations: 1. Edge dislocation 2. Screw ______

Edge dislocation: an extra portion of a plane of atoms, or half-plane, the edge of which terminates within the ______.

The magnitude and direction of the lattice distortion associated with a dislocation are expressed in terms of a Burgers vector, denoted by ______.
