Abstract
The characteristics of the Al/SiC interface play a critical role in controlling the properties of SiC-reinforced aluminium composites and aluminium-brazed SiC ceramic joints. Recently, a detailed investigation on the wettability of SiC single crystals by aluminium and several of its alloys was conducted. In order to understand further the nature of the Al/SiC interface, high resolution and conventional transmission electron microscope techniques have now been used to investigate its microchemistry and microstructure. The results revealed the coexistence of two polytype structures, rhombohedral and hexagonal, in the SiC single crystal structure. Aluminium carbide (Al4C3) and silicon were the reaction products found at the Al/SiC interface. From diffraction patterns, epitaxial orientation relationships between the SiC substrate and Al4C3, Si were determined.
