W-ZrC composite powders were prepared by sol-heterogeneous precipitation-spray drying thermal reduction technology. W-ZrC material was prepared by high temperature sintering under hydrogen atmosphere. Effect of ZrC content on the microstructure and properties were investigated. The results show that the relative density of W-ZrC material is greatly improved compared with that of pure W, the room temperature tensile strength of W-ZrC material is twofold of pure W , which is 290MPa. And the strain of the material is increased from 1.7% to3.5%. The second phase particles of ZrC can effectively prevent the migration of grain boundary. The grain is refined from 100μm to 10-15μm. The fracture morphology of pure W is mainly intergranular fracture, but W-ZrC materials is visible in transgranular brittle fracture. ZrC can effectively enhance the strength of the grain boundary of W, and has good effect in fine grain strengthening and dispersion strengthening.
