Abstract. Changes in crystal structure of metal at action of variable tension are considered. The description of the mechanism of formation of dislocations is given. On the basis of the dislocation theory process of emergence and development of cracks of fatigue is described. The main processes which are the cornerstone of fatigue failure are listed and grouped.

Keywords: durability, crystal lattice, dislocations, shift processes, fatigue cracks
