Summary

Ti3SiC2-TiC composites with graded interfaces have been processed through a high-temperature vacuum heat-treatment. X-ray diffraction (XRD), synchrotron radiation diffraction (SRD) and neutron diffraction (ND) have been used to characterise the phase evolution and the graded composition in mis system. Results of SRD and ND in the temperature range 1000–1500°C show that the TiC layer commenced to form near the surface at 1200°C and grew rapidly in thickness with rising temperature. Depth-profiling of the TiC layer by XRD and SRD has revealed a distinct gradation in phase composition.
