AB  - Tungsten is the main candidate for the plasma-facing material in future fusion reactors. To overcome the brittleness of tungsten, tungsten fiber-reinforced tungsten (Wf/W) composites have been developed using a powder metallurgy process. In this study, a novel type of Wf/W with a porous matrix has been developed using field-assisted sintering technology. Compared with conventional Wf/W, the avoidance of a fiber–matrix interface simplified the production process. Initial mechanical testing showed that Wf/W with a porous matrix can establish a promising pseudo-ductile behavior with an increased fracture toughness compared with pure tungsten.
