“…The two potential methods to manufacture W f /W composites are chemical vapor deposition (CVD) [7,14] and powder metallurgy processes (PM) [15][16][17][18]. Both production routes have shown the possibility to achieve the expected pseudo ductility.…”

“…The ultra-fine grained (UFG) tungsten fabricated by equal channel angular pressing (ECAP) can achieve nanostructured grains, reflecting good mechanical properties at room temperature [12]. Meanwhile, the fiber reinforced tungsten composites exhibit enhanced fracture toughness and thermal stability [13][14][15]. But these processes are not suitable for producing industrial scale products.…”

“…The chemical composition of the fibres is given in our previous work [16,24]. The theoretical density of the W fibres can be considered as 19.3 g/cm 3 , as same as the value of pure tungsten.…”

“…The enlarged picture at the part I in Figure 1b is shown in Figure 1I for clarity. In this work, each sample contained four tungsten-fibre-net layers according to the optimization of fibre contents in our earlier work [24]. Pure tungsten powders (purity > 99.9%, average particle size 600 nm) were ball-milled for 4 h in a planetary ball mill in argon atmosphere to increase the activity with a powder-to-ball weight ratio of 1:8 and rotation speed of 240 rpm.…”
