Abstract—A study was made of the structure of a VT41 titanium alloy (Ti–Al–Si–Zr–Sn + β stabilizers) subjected to hot upsetting in the (α + β) region, i.e., under conditions simulating the forging process of a disk used for a gas turbine engine (GTE). It reveals the features of the textural state formation of primary and secondary globular grains, as well as the kinetics of their dissolution with increasing annealing temperature. The homogeneity of the billet structure resulting from heat treatment at 995°C increases substantially compared to the deformed state, which is related to the recrystallization of lamellar and small-globular grains and the retention of primary globular grains of the α phase. The sequence of structural changes upon heating is determined in the annealing temperature range from 950 to 1040°C.
