W-ZrC materials were prepared by ordinary consolidation sintering. The effects of ZrC addition on the mechanical properties and microstructure of the materials at room temperature and high temperature were studied, and the damage behavior under high heat flux shock was studied. The results show that ZrC is beneficial to densification and grain refinement, and improve the strength and toughness of W materials. The relative density and tensile strength of W-3wt%ZrC can reach 99.7% and 472MPa. The relative density and room temperature tensile strength of W-3wt%ZrC were 99.7% and 472MPa, respectively, and the tensile strength at 400 to 1000 C did not decrease at 420MPa, but the strain increased from 3.4% at room temperature to 11% at 1000 C. High heat flux shock show that high strength can improve the impact resistance of materials against high heat load. The surface of W-3wt%ZrC material has no cracks load under high heat flux shock of 200 MW/m2 (5 ms). The main crack spacing of W-3ZrC is smaller than W-0.7wt%ZrC at 300-400MW/m2. With the increase of the high heat load energy, the cracks gradually expand along the longitudinal direction. Microstructure shows that ZrC can consume the crack propagation energy and hinder crack propagation.
