We employed transmission electron microscopy and atom probe tomography to reveal structural and compositional evolutions of precipitation in HfNbTaTiZr upon isothermal aging at 1200 °C. Due to the presence of O in the atmosphere, a Zr-Hf-rich hexagonal closed-packed (hcp) phase precipitates from the bcc matrix after 200 h. Due to the gradual uptake of O by the alloy from 200 h to 500 h, the Ti and O concentrations of the hcp phase increase. This results in the formation of an ordered phase in the hcp phase with a structure similar to Ti<sub>3</sub>O, whose number density and size slightly increase with time.
