In this study, chromium carbide-nickel composites were fabricated by mixing pure Cr 3 C 2 and Ni powders at 1250, 1275, 1300 and 1325 °C for 1 h. The effects of the Ni content on the microstructures and mechanical properties of these composites were researched. Both Cr 3 C 2 and Cr 7 C 3 showed a well-defined crystallographic orientation. Two groups: (002) Cr3C2 //(004) Cr7C3 and [ 2 ‾ 10 ] Cr 3 C 2 // [ 2 ‾ 10 ] Cr 7 C 3 were observed. The porosity of the specimens first declined and then risen slightly with an increase in the Ni content. The micro-hardness of the specimens showed an opposite trend. The bending strength and fracture toughness of the specimens first risen with an increase in the Ni content and then decreased, thus changing the fracture mechanism from inter-granular fracture to trans -granular fracture. The optimal temperature was 1300 °C and the composite with 20 wt% Ni showed the best mechanical properties. [ABSTRACT FROM AUTHOR]
