Abstract  

As a candidate for plasma facing material (PFM) in nuclear fusion situation, polycrystalline W with a characteristic of bad low temperature ductility shows brittle behaviour at room temperature and possesses a high ductile-to-brittle transition temperature, which limits its engineering application. In this paper, several common methods of grain refinement, addition of alloying elements, second-phase particles and tungsten fibre, and deformation processing for improving ductility of W are illustrated. To in-depth comprehend of how to improving W toughening, these toughening methods are discussed from intrinsic or extrinsic toughening mechanisms. Furthermore, the research status and development prospects for improving ductility of W materials have been presented.

Key words:  plasma facing material      W      toughening mechanism      mechanical performance      intrinsic toughening      extrinsic toughening
