•Deoxidation behavior during preparation of low oxygen Ti powder was discussed.•The oxide layer reduced to a thickness of 3 nm from 11 nm after deoxidation.•The oxygen content within the Ti powder also decreased after deoxidation.•The lattice parameters and axial ratios of the titanium powder decreased as well.•No increase in the oxygen content after exposure to air for one month.
Deoxidation behavior before and after deoxidation during preparation of low oxygen titanium powder was discussed. Transmission electron microscopy and secondary ion mass spectraoscopy studies revealed that the oxide layer was reduced to a thickness of 3 nm from 11 nm and the oxygen content within the powder was decreased from 2500 ppm to 920 ppm. The reduction of oxygen content resulted in the decrease of the lattice parameters and axial ratios. The surface oxide of deoxidized powder was quite stable in air showing no increase in the oxygen content after the exposure for one month.
