  title = {Blistering and retention behavior of laser powder bed fused tungsten alloys under hydrogen plasma irradiation},
  abstract = {In this study, pure tungsten (W) fabricated by powder metallurgy and laser powder bed fusion (LPBF) formed W-Ta and W-ZrC alloys were exposed to hydrogen plasma. Severe blistering was found in LPBFed W-Ta specimens due to a strong [111] crystallographic texture and the large number of particle-matrix interfaces in the LPBFed W-ZrC inhibits the blister growth. The retention of LPBFed W alloys is lower than that of pure W due to the presence of large columnar grains and cracks. The results highlight the capability of tailoring the microstructures of W alloys by the LPBF technique to achieve improved plasma-compatible performance.},
