Question

Explain interstitial defect and its effect on
properties of metal.

Answer 1

Answer:

As a result, point defects often determine the properties of a material. They can change the ease with which a material conducts electricity, its mechanical strength, its ability to be shaped by hammering (malleability), or to be drawn into wires (ductility).

Answer 2

An interstitial defect is a type of point crystallographic defect where an atom of the same or of a different type, occupies a normally unoccupied site in the crystal structure. When the atom is of the same type as those already present they are known as a self-interstitial defect. Alternatively, small atoms in some crystals may occupy interstitial sites, such as hydrogen in palladium. Interstitials can be produced by bombarding a crystal with elementary particles having energy above the displacement threshold for that crystal, but they may also exist in small concentrations in thermodynamic equilibrium. The presence of interstitial defects can modify the physical and chemical properties of a material.
