Using a high‐resolution Auger microprobe the chemical structure of the interface in a SiC reinforced titanium alloy has been examined. Only two phases, TiC and Ti 5 Si 3 , are identified in the interface. A TiC layer next to the SiC fiber was proven to form a diffusion barrier for titanium. The results aid in the understanding of the fiber surface degradation process during sample production and suggests processes for the further development of these composites.
