英文摘要	W-Lu2O3 and W-Nb-C-Lu2O3 composites were fabricated by mechanical milling and spark plasma sintering. The morphology of composite powders, surface and fracture surface morphology of the samples were characterized by field-emission scanning electron microscopy (FE-SEM), energy-dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). The relative density, thermal conductivity, hardness and strength of the samples were also measured. Results reveal that the addition of trace Nb and C on the basis of W-Lu2O3 composite has an obvious effect on grain refinement, densification and strength increasing. The relative density of W-Nb-C-Lu2O3 composite is 5.75% higher than that of W-Lu2O3 and reaches 95.12%. The grain size of W-Nb-C-Lu2O3 composite is refined from 8-13 mu m to 2-5 mu m, and its microhardness and strength are significantly improved compared with that of W-Lu2O3 composite.
