Resumo
The microstructure evolution and mechanical behavior of the two-phase titanium VT8M-1 alloy with initial globular-lamellar structure are investigated during compression in the temperature range of 650–800°C at a strain rate of 1.4 × 10–3 s–1. It is established that the microstructure evolution of the alloy during compression is associated with the development of globularization and dynamic recrystallization of α-phase lamellae with subsequent formation of globular-shaped particles. The extent of the steady-state flow stress and the average size of recrystallized α-phase particles in the alloy increase as the temperature of plastic deformation is increased from 650 to 800°C. The possible formation of ultrafine-grained structure in the VT8M-1 alloy in the studied temperature–rate conditions of plastic deformation is shown.
