Defects Course

Study the concept of crystal defects in solid materials, point defects, line defects: dislocations, two-dimensional defects: interfaces, and volume defects. The simplest point defect is a vacancy, where there are missing atoms in the crystal. Interstitial self is generally known as Frenkel-Defect and vacancy of ion pairs is known as Schootky-Defect. Material defects can be overcome by heat treatment until it reaches the recrystallization temperature. An overview of the mechanical properties of materials will also be studied: the stress-strain graph (Young‘s modulus) which is associated with the phenomenon of defects in solid material bodies and their mechanical properties (strength of materials). Phase transformations due to hot and cold treatment (heattreatment, aging) will also be discussed.
