We establish the regularities of the kinetics of phase and structural transformations in complex titanium alloys in different states (forged and cast) after holding in the one-phase β-region. Two temperature ranges with different kinetics of the polymorphic transformation are detected. In the high-temperature range, the β-phase decays according to the diffusion mechanism with formation of several metastable phases in specimens quenched at the same temperature after different periods of holding. In the low-temperature range, the phase transformation runs fairly rapidly with formation of a two-phase dispersed structure. It is shown that the rate of the process and the geometric parameters of the formed structures are determined not only by the total concentration of alloying elements but also by their composition. The obtained results can be used for the development of new efficient modes of thermal treatment.
