摘要：
The article provides results of studying the influence of production parameters of prior heat treatment on structure and phase composition of sheets of metastable beta-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 (alpha + beta) 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.
