The structure and mechanical properties of the Ti-Nb-Mo titanium alloys and alloys on the basis of them were investigated, and the alloy with a low Young modulus (~ 55 GPa) and high strength (950 MPa) was obtained. The regime of heat treatment of alloys which leads to a decrease in the modulus of elasticity by ~ 1.5 times has been developed. Fragments of the Zr-Co-Sn system phase diagram were first constructed at melting temperatures of alloys with 5 at. % Sn, and it was found that the phase based on alfa zirconium was sufficiently hard, plastic, and possess satisfactory heat resistance. For the Zr-Nb-Sn alloys, the technology of introduction of nanosized particles Y2O3 (40 nm) and ZrO2 (5 nm) was developed and the mechanism of their nanophase hardening at 400-600°C was established. The alloys Zr-8Al and Zr-8Al-1Nb (in wt.%) with high Zr3Al content were obtained and the mechanisms of their creep in the temperature range 400-600°C were established according to the results of stress relaxation tests and creep resistance diagrams.
