Abstract Oxidation behavior of titanium alloy Ti600 at 700–1000oC as investigated. Results howed that the oxidation kinetics of the Ti600 alloy followed the parabolic-linear law and the activation nergy of oxidation was 224 kJ·mol−1 under the condition of oxidation at 700–1000oC for 100 h. ense oxide scales formed on the sample surface at 700oC for 100 h, while oxide scales with multilayer icrostructure formed at the temperature above 700oC began spalling. Oxide scales mainly compose f rutile and α–Al2O3. Oxidation diffusion zone (ODZ) beneath oxide scale has sub-layer microstructure ormed at 700–1000oC. The thickness of ODZ sub-layers and oxygen solubility in ODZ increased with the ncrease of oxidation temperature and prolonging of the oxidation time.
