Metals can have various types of defects. A point defect is any defect that involves only a single particle (a lattice point) or sometimes a very small set of points.

At any temperature above 0°K, the free energy is a mini­mum for a certain concentration of defects determined by the balance of The conditions under which submicroscopic defects can be revealed due to decoration by the precipitation of vacant lattice sites from a supersaturated solution have been investigated in aluminium.

Two particular defects, rows of loops along directions end narrow faulted dipoles with their axes along the same direction, were studied in specimens quenched to and deformed at low A.M.

Kosevich jointly with Prof. I.M. Lifshits determined a quantitative relation between the de Haas-van Alphen oscillations and the shape of the Fermi surface for electron gas in metals (Lifshitz-Kosevich formula).

A general discussion has been made on the factors which determine the type, number and size of secondary defects which are formed by vacancies in quenched face-centered cubic metals. A method of analysis, which uses the positive (growth) and negative (shrink) reaction ratios, has been introduced.

This method is especially applicable for the analysis of the formation of such secondary defects Since the field of point defects is rather different from the field of dislocations we will only give a few short indications about the former here.
