W-Y2O3-ZrO2 composite materials were fabricated by a combination of wet chemical method and spark plasma sintering. We systematically studied the W-Y2O3-ZrO2 composite materials at different Y and Zr doping atomic ratios. The ultrafine tungsten-based composites with a dispersed distribution of Y2Zr2O7 particles can be prepared by appropriate Y and Zr doping atomic ratios for this experiment. The surface evolution behavior of W-5Y-5Zr composites induced by high temperature annealing and helium ion irradiation was investigated. The nano-Y2Zr2O7 second-phase particles greatly increased the resistance of the material to grain growth. The dispersed and fine of Y2Zr2O7 particles in the tungsten-based composites effectively improved the resistance to helium ion irradiation. These findings can serve as a reference for the fabrication of tungsten-based materials in fusion engineering. (C)& nbsp;2022 Elsevier B.V. All rights reserved.
