The regularities of the influence of deformation and phase composition, hardening and plasticity of Nb-Ti-Al-Cr-Zr-Mo-Si alloys were determined, which are explained by the effects of dynamic deformation aging, dynamic recrystallization and manifestations of superplasticity in the deformation process. The alloy with a specific weight of 6.4 g /cm3 was obtained, it has at 1200 ° C a flow limit of 420 MPa, and elongation 3-5% at 20 ° C The alloy was melted by the Ti-Technology LLC enterprise. The blanks of the obtained alloy were transferred to KB Progress for the production of working and nozzle blades of the AI-450 engine.
