It is shown that the topological features of the electronic structure of α-titanium lead to the appearance of temperature-induced fluctuations of the electron density, which disappear near the temperature of the phase transition from the hcp (α-phase) to the bcc (β-phase). The experimen-tally observed linear temperature increase in the magnetic susceptibility in the beta-phase and its jump during the transition to the β-phase are described. The considered fluctuation pattern de-scribes a sharp decrease in the electron entropy and softening of the longitudinal phonon modes associated with the electron-ion interaction. It is shown that the temperature of the phase transition in α-titanium depends on the position of the Fermi level, which can be changed by introducing impurities.
