Abstract
The article provides results of studying the influence of production parameters of prior heat treatment on structure and phase composition of sheets of metastable β‑titanium alloy VT47 manufactured under industrial production conditions. As a result of research experimental methods of combined high- and low-temperature thermomechanical processing of alloy VT47 sheets are developed and their structure and mechanical properties in a thermally hardened state are studied. It is shown that methods of combined TMT of VT47 alloy, including annealing in the two-phase (α + β) region and ageing after rolling, make it possible to provide the required structure of a globular-lamellar type and a balanced set of mechanical properties.
