W–Zr/Sc₂O₃ composites with different Zr doping content were produced through powder metallurgy (PM) and subsequent spark plasma sintering (SPS) at 1700 °C. The thermal conductivity of composites decreased initially and then increased as the Zr content increased. Afterwards, the thermal shock behavior of W–Zr/Sc₂O₃ composites under transient event was investigated. Repeated electron irradiations cause significant surface roughening, cracks, and extruded structures. These surface modifications are attributed to plastic deformation and thermal fatigue. Results reveal that W-1%vol Zr/2%vol Sc₂O₃ has superior thermal properties and great resistance to surface modifications under repeated high heat-load.
