Increasing the strength of marine titanium alloys by solid solution and structural hardening

https://doi.org/10.22349/1994-6716-2024-120-4-17-25

Abstract

The paper investigates ways of increasing the strength of the experimental high-alloy titanium alloy having a thermally unstable β-phase in the structure at room temperature. It is shown that solid solution and structural strengthening leads to a change in the phase and intrastructural state of the material under study, which, in turn, ensures an increase in strength characteristics. At the same time, depending on the annealing mode, an increase in the conditional yield strength from 1000 to 1200 MPa is ensured without a significant decrease of viscoplastic properties.
