Abstract

Tungsten can be the preferred plasma-facing material for nuclear fusion reaction. In this work, W-Y ₂ O ₃ composite powder was successfully fabricated through the wet chemical method, and bulk materials were obtained by rolling and high temperature annealing. W-2 vol% Y ₂ O ₃ was exposed to 80 eV helium ion irradiation with a flux of 1.5 × 10 ²² ions/(m ² ·s) at 1503–1553 K to assess its thermal shock resistance and helium ion irradiation damage behavior. The thermal shock behaviors of samples were studied under a laser beam. The energy densities of the laser thermal shock were 0.32, 0.48, and 0.64 GW/m ² . W-Y ₂ O ₃ was compared with commercial pure tungsten. The hardness of pure tungsten and W-Y ₂ O ₃ before and after helium irradiation was measured by using a micro-hardness tester. The surface micrograph after helium ion irradiation and thermal shock was observed through scanning electron microscopy. Results show that W-Y ₂ O ₃ composite materials have better resistance to laser thermal shock than pure tungsten.
