The collection includes articles on the problem of physical chemistry and metallurgy of titanium alloys with special properties. The physical properties of alloys based on titanium and its chemical compounds are considered - thermophysical, acoustic, elastic, electrophysical, including in the microwave range, the effect of "shape memory" depending on the structure and phase composition in equilibrium and non-equilibrium, including in amorphous, amorphous-crystalline and ultrafine states (after quenching from a liquid state).
