Question

Imperfection in crystal and its mechanical properties

Answer 1

Imperfections include vibrations and rotations due to thermal energy, point defects (vacancies, interstitials, substitutional solutes), linear defects (edge and screw dislocations), boundary or surface defects (grain boundaries and phase boundaries, including surfaces), and three-dimensional defects (amorphous or liquid state)

properties such as resistivity/conductivity also depend on the imperfections in metals.
