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.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
