Abstract:Ti/Al2O3functional gradient materials (FGM) were prepared using explosive compaction plus SHS method. The microstructure, composition and properties of the prepared FGM were investigated. The results showed that the gradient distribution concerned with the microstructure, composition and properties of this FGM was in good agreement with the designed model, and the density of the FGM was improved, the reaction model of each gradient layer in SHS process was also discussed.
Key words: FGM explosive compaction SHS Ti/Al2O3
