Tungsten Wire—From Lamp Filaments to Reinforcement Fibers for Composites in Fusion Reactors

Tungsten Fiber-Reinforced Composites In article number 2400951, Johann Riesch, Maximilian Fuhr, and Jürgen Almanstötter present a review which illuminates the unlikely revival of tungsten wire, from its iconic role as coils in incandescent bulbs to its emerging applications in high-performance composites for nuclear fusion reactors. This includes new insights into its unique combination of strength, ductility, and high-temperature properties, which are key properties for the excellent fracture behavior of tungsten fiber-reinforced composites. The authors discover how this versatile material is being reengineered and what new applications are emerging from cutting-edge research.
