It is intended to describe the use of positron annihilation spectroscopy in metals and alloys. In the sections following the introduction of the basic principles, applications of positron annihilation are presented to study defect and defect-free materials. The investigation of Fermi-surface properties in single crystals of metals and alloys is one of the very interesting topics in positron annihilation. Even more exciting and in some way unique is the positron method in the field of defects in metallic materials, such as vacancies in thermal equilibrium, quenched-in defects, dislocations, grain boundaries associated with phase transitions, amorphous structures, and radiation-induced defects and their agglomerates, together with implanted gases.    «
