Abstract:
The influence of Fe content on the properties of TiC-Al
2O
3/Fe composites prepared by SHS/PHIP was studied. The results show that the TiC-Al
2O
3/Fe cermets prepared by SHS/PHIP possess high mechanical properties such as well-improved flexural strength and fracture toughness owing to the addition of Fe, and highly special stiffness. The TiC-Al
2O
3 ceramic exhibits the typical brittle fracture behavior. However, the TiC-Al
2O
3/Fe cermets exhibit obvious characteristic of tough fracture with Fe content increasing.
