Abstract : The study concerns the properties of alloy 4201 (titanium with 32-35% molybdenum) and certain laws governing the change in its mechanical characteristics at higher temperatures. All studies were carried out on rod and sheet material. All sheet material samples were tested in the original state (vacuum annealing at 850, holding - one h, cooling in the furnace to 400, then in air). Forged rods were preannealed at 850 for one h and then air cooled. According to the data of microstructural analysis, before the tests the samples of alloy 4201 (from the rod and sheet) had a polyhedral structure of solid solution based on body-centered beta - titanium and molybdenum lattice.
