“…Both models predicted the texture better for moderate deformation and slightly differed for large deformation, but were qualitatively consistent. Na-na Qiu et al [81] prepared two tungsten rhenium alloy wires with different crystal sizes and investigated the microstructure and tensile properties of coarse (C-WRe) and fine (F-WRe) alloy wires from room temperature to 800 • C. Figure 21 Above all, the large deformation process of the material leads to work hardening, and the plasticity is greatly reduced, which is not conducive to the subsequent processes. However, after annealing, the material recrystallizes, which effectively improves the internal crystal structure, decreases the strength and improves the plasticity.…”

In light of the fact that tungsten wire is gradually replacing high-carbon steel wire as a diamond cutting line, it is particularly important to study tungsten alloy wire with better strength and performance. According to this paper, in addition to various technological factors (powder preparation, press forming, sintering, rolling, rotary forging, annealing, wire drawing, etc.), the main factors affecting the properties of the tungsten alloy wire are the composition of the tungsten alloy, the shape and size of the powder, etc. Combined with the research results in recent years, this paper summarizes the effects of changing the composition of tungsten materials and improving the processing technology on the microstructure and mechanical properties of tungsten and its alloys and points out the development direction and trend of tungsten and its alloy wires in the future.

“…In order to improve the mechanical properties of brittle materials such as W several options had been considered: microstructural refinement, alloying or composites [11][12][13][14][15][16][17]. Here we are briefly summarizing the W f /W.…”

Material related limitations are one of the main challenges for the design of future fusion reactors. Tungsten (W) as the primary material choice is considered resilient against erosion, has the highest melting point of any metal and shows low activation after neutron irradiation. However, W is intrinsically brittle and faces operational embrittlement. To overcome these issues, W-based composites have been in development. W fiber-reinforced W composite materials (W f /W) incorporate extrinsic toughening mechanisms allowing the redistribution of stress peaks and thus overcoming the intrinsic brittleness problem. In this contribution recent results on the incorporation of new textile preformes into W f /W production will be given with a focus on the production via chemical vapor deposition of tungsten-based materials. The use of tungsten yarns, instead of single wires for the textile production is elaborated.

“…Alloying with rare earth elements to optimize the performances of W material is also becoming popular among various alloying strategies [7,[17][18][19][20]. Previous works have confirmed that rare earth elements offer high chemical affinity for oxidation in W. For example, the rare earth oxides of La 2 O 3 , Y 2 O 3 and CeO 2 are formed when the elements of La, Y or Ce are added in W [7,11,[18][19][20].…”

Tungsten (W) is considered as the potential plasma facing material of the divertor and the first wall material in fusion. To further improve the ductility of W, the structural and mechanical properties of W–M (M = rare earth element Y, La, Ce and Lu) alloys are systematically investigated by first-principles calculations. Our results reveal that all the W1−xMx (x = 0.0625, 0.125, 0.1875, 0.25) alloys can form binary solid solution at the atomic level, and the alloys keep bcc lattice structures until the concentration of M increases to a certain value. Although the moduli of the alloys are reduced compared to that of pure W metal, the characteristic B/G ratio and Poisson’s ratio significantly increase, implying all the four rare earth elements can efficiently improve the ductility of W metal. Considering both factors of mechanical strength and ductility, La and Ce are better alloying elements than Y and Lu.
