Abstract

The oxidation behavior of Nb-base in situ composites in static air at 1100, 1200 and 1250 °C has been studied. The reaction followed the parabolic rate law. The oxide scales were mainly composed of TiNb₂O₇, TiNb₁₀O₂₉, TiO₂, Nb₂O₅ and SiO₂. The theoretical oxidation model proposed by Gesmundo et al. has been applied to analyze existing oxidation data of Nb-base in situ composites. The result shows that oxidation rate of the Nb-base in situ composites is basically accordance with the analytical results predicted by the theoretical oxidation model to a good approximation.
