Abstract : The purpose of the present study is research of a fundamental nature in order to further our knowledge about high-temperature oxidation behavior of structural, titanium-base alloys operating above 900C. Oxidation characteristics of Ti-4.45 Cb, Ti-4.37 Ta, Ti-(4.0 and 6.0) Al, and Ti-4.0 Sn, all in wt.%, are reported for the temperature range 900 to 1150C. Data obtained from thermogravimetric measurements and supplemented by results from x-ray diffraction, electron-probe microanalyses, hardness measurements, and metallographic examinations indicate that Ti-4.45 Cb and Ti-4.37 Ta alloys exhibit the best oxidation resistance under the used experimental conditions.
