Abstract : The purpose of the study was 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-4.32 wt.% Cb and Ti-4.37 wt.% Ta alloys are reported for the temperature range 1000-1200C. The influence of oxygen pressure of 10, 100, and 760 torr on the oxidation kinetics of Ti-4.37 wt.% Ta, as well as sintering effects in the oxide are also investigated. The oxidation behavior of Ti-4.32 wt.% Cb in dry, oxygen and air at 1000 and 1100C is reported. (Author)
