This work systematically summarized the cyclic deformation behaviors of various types of face-centered cubic single crystals, including copper, nickel, silver, as well as copper–aluminium, copper–zinc alloys, in attempt to provide an historical perspective of developments over the last several decades. Combined with plenty of previous research results, the influencing factors on cyclic deformation behaviors could be listed as follows: orientations, stacking fault energy, short-range order and friction stress, or more generally, the ease of cross slip. Among them, the effect of orientations mainly reflects in the formation of the complex dislocation patterns, which depends on the activating secondary slip system. According to the effect of slip mode, the materials could be divided into two types: pure metals and alloys. For pure face-centered cubic metals, the effect of stacking fault energy was decisive. Due to the easy cross slip of screw dislocations, regular dislocation arrangements, e.g. veins, persistent slip bands, labyrinth and cell patterns, were always to form. With increase in alloying element, antiphase boundary energy gradually replaces stacking fault energy to become a new decisive factor affecting the cyclic deformation behaviors of face-centered cubic alloy single crystals. The corresponding dislocation arrangements consist of dipole array and stacking faults under the influence of planar slip. The relationship among several factors was well explained, and helped to clarify the nature of the fatigue damage of metallic materials.
