| Abstract | The oxidation characteristics, composition profile and phase transition of Ti3SiC2 in the temperature range 20-1400°C have been investigated by in-situ neutron diffraction and secondary ion mass spectroscopy (SIMS). Anatase has been observed to form at ~600°C, rutile at ~750°C and cristobalite at ∼1300°C. Depth-profiling results by SIMS and Vickers indentation have revealed a distinct gradient in composition and microhardness within the surface oxide layers. |
