Abstract
The microstructure and chemical composition of phases and inclusions in Ti–5Al–4V–2Zr alloys are studied in the initial state, after irradiation by titanium ions to radiation damage dose of ~1 dpa at 260°C, and after thermal aging at 450°C for 1000 h. Microstructural studies are carried out using scanning electron microscopy and atom probe tomography. Phase analysis is performed using energy dispersive X-ray spectroscopy. Chemical analysis of grains of the matrix phase and β-phase is presented. Spatial distribution of chemical elements in α- and β-phase lamellae is analyzed by atom probe tomography. Formation of nanosized vanadium pre-precipitates in the α-phase is observed in irradiated material.
