Abstract TiC and WC/TiC were added into Fe-1.5Cu-1.8Ni-0.5Mo-1C and Fe-1.5Cu-0.7C. Composites were prepared
by conventionally mixed powder in mesh belt sintering furnace. Material properties were tested including microscopic
pore morphology, density, hardness and bending strength. The results show that compared with WC, the
interface bonding between TiC and Fe-1.5Cu-1.8Ni-0.5Mo-1C/Fe-1.5Cu-0.7C is poorer. When TiC is added, materials
have the worst performance, which declines as TiC content increases. When WC is added, materials have the
best performance, which first increases and then decreases with the increasing of WC content. When TiC and WC
are added at the same time, materials have the moderate performance, which also declines as TiC and WC content
increases. Under the experiment condition of this paper, adding the right amount of WC to Fe-1.5Cu-1.8Ni-0.5Mo-
1C/Fe-1.5Cu-0.7C as reinforcing particles may be a better choice.
