The diagrams of continuous cooling transformation (CCT) of β-phase decomposition for hot-rolled VT8M titanium alloy were obtained using the differential thermal analysis, scanning electron microscopy, and X-Ray diffraction (XRD) analysis for heating temperatures from 880 to 960 °C. The decomposition process was found to occur with several distinguishable stages. The transformation begins from high-temperature stage of the growing of primary alpha precipitates. At lower temperatures, it is followed by the medium-temperature stage accompanied by precipitation of grain-boundary alpha and the formation of coarse secondary alpha-lamellae. The low-temperature stage has been established to be characterized by the formation of dispersed alpha-platelets within beta-grains. |
