CCT-diagrams of beta-phase decomposition for hot-rolled VT8M titanium alloy were developed by differential thermal analysis, scanning electron microscopy and microhardness measurements for heating temperatures in range 880°C…960°C. The beta-phase decomposition during continuous cooling was found to have three distinguishable stages. The transformation begins from high-temperature stage that is heterogeneous and proceeds by means of growth of the primary alpha-phase. It following to the middle-temperature stage accompanied by formation of grain-boundary alpha-phase and coarse secondary alpha-lamellae. A low-temperature decomposition stage was established to characterized by formation of dispersed alpha-lamellae.
