Researchers have found that refining the grain can significantly improve the strength and the irradiation resistance of W/W-based materials. In this paper, novel approaches and technique routes, including the “bottom-up” powder metallurgy method and “top-down” severe plastic deformation method, are introduced to the fabrication of nanocrystalline W/W-based materials. The formation mechanisms of nanocrystalline W/W-based materials were revealed, and the nanostructure stabilization mechanisms were introduced. The mechanical properties of nanocrystalline W/W-based materials were tested, and the irradiation behaviors and performances were studied. The mechanisms of their high mechanical properties and excellent irradiation-damage resistance were illustrated.
