In this review the precipitation phenomenon and age-hardening response in Cu–Ti alloys founded on the Ukrainian and Russian authors investigations mainly was discussed. At that point, it was especially underlined that a mechanism of the early stage of the decomposition was not as spinodal one (American authors point of view) but more likely as a nucleation of fine-scale coherent precipitates of the metastable α′-phase (Cu4Ti). The kinetics of the continuous and discontinuous (cellular) precipitation; the morphology of the metastable α′-phase and stable β-phase precipitation; an influence of the external effects (plastic and ultrasonic deformation, external pressure, radioactive irradiation) on these processes; the nature of the high age-hardening response in Cu–Ti alloys and the reversion phenomenon was considered. It was postulated that these alloys could replace the beryllium bronze successfully according to their mechanical properties.
