Interfacial characterisation in Al–20 vol.-%SiC_p explosively compacted composite

Abstract

Al–20 vol.-%SiC_p composite was prepared using direct explosive compaction. Interfacial characterisation of the composite was preformed using scanning electron microscopy, X-ray diffraction and transmission electron microscopy. The results showed that the interface seemed to be clean and no interfacial Al₄C₃ reaction product was generated along the interface between SiC particles and Al matrix. The results also showed a better bonding between SiC particles and Al matrix in the central region of the compact sample.
